Meta-Analysis Review
OBJECTIVE
This study aimed to quantify the association between mode of operative delivery in the second stage of labor (cesarean delivery vs operative vaginal delivery) and spontaneous preterm birth in a subsequent pregnancy.
DATA SOURCES
MEDLINE, Embase, EmCare, CINAHL, the Cochrane Library, Web of Science: Core Collection, and Scopus were searched from database inception to April 1, 2023.
STUDY ELIGIBILITY CRITERIA
All retrospective cohort studies with participants who had a second-stage cesarean delivery (defined as intrapartum cesarean delivery at full cervical dilation) or operative vaginal delivery (including forceps- and/or vacuum-assisted delivery) and that reported the rate of preterm birth (either spontaneous or not specified) in subsequent pregnancy were included.
METHODS
Both a descriptive analysis and a meta-analysis were performed. A meta-analysis was performed for dichotomous data using the Mantel-Haenszel random-effects model and used the odds ratio as an effect measure with 95% confidence intervals. The risk of bias was assessed using Cochrane's 2022 Risk Of Bias In Non-randomized Studies of Exposure tool.
RESULTS
After screening 2671 articles from 7 databases, a total of 18 retrospective cohort studies encompassing 605,138 patients were included. The pooled rates of spontaneous preterm birth in a subsequent pregnancy were 6.9% (12 studies) after second-stage cesarean delivery and 2.6% (8 studies) after operative vaginal delivery. A total of 7 studies encompassing 75,460 patients compared the primary outcome of spontaneous preterm birth after second-stage cesarean delivery vs operative vaginal delivery in an index pregnancy with an odds ratio of 2.01 (95% confidence interval, 1.57-2.58) in favor of operative vaginal delivery. However, most studies did not include important confounding factors, did not address exposure misclassification because of failed operative vaginal delivery, and considered operative vaginal delivery as a homogeneous category with no distinction between forceps- and vacuum-assisted deliveries.
CONCLUSION
Although a synthesis of the existing literature suggests that the risk of spontaneous preterm birth is higher in those with a previous second-stage cesarean delivery than in those with operative vaginal delivery, the risk of bias in these studies is very high. Findings should be interpreted with caution.

Meta-Analysis
OBJECTIVE
To assess the comparative effectiveness and potential harms of cervical ripening in the outpatient compared with the inpatient setting, or different methods of ripening in the outpatient setting alone.
DATA SOURCES
Searches for articles in English included MEDLINE, EMBASE, CINAHL, Cochrane Library, ClinicalTrials.gov, and reference lists (up to August 2020).
METHODS OF STUDY SELECTION
Using predefined criteria and DistillerSR software, 10,853 citations were dual-reviewed for randomized controlled trials (RCTs) and cohort studies of outpatient cervical ripening using prostaglandins and mechanical methods in pregnant women at or beyond 37 weeks of gestation.
TABULATION, INTEGRATION, AND RESULTS
Using prespecified criteria, study data abstraction and risk of bias assessment were conducted by two reviewers, random-effects meta-analyses were conducted and strength of evidence was assessed. We included 30 RCTs and 10 cohort studies (N=9,618) most generalizable to women aged 25-30 years with low-risk pregnancies. All findings were low or insufficient strength of evidence and not statistically significant. Incidence of cesarean delivery was not different for any comparison of inpatient and outpatient settings, or comparisons of different methods in the outpatient setting (most evidence available for single-balloon catheters and dinoprostone). Harms were inconsistently reported or inadequately defined. Differences were not found for neonatal infection (eg, sepsis) with outpatient compared with inpatient dinoprostone, birth trauma (eg, cephalohematoma) with outpatient compared with inpatient single-balloon catheter, shoulder dystocia with outpatient dinoprostone compared with placebo, maternal infection (eg, chorioamnionitis) with outpatient compared with inpatient single-balloon catheters or outpatient prostaglandins compared with placebo, and postpartum hemorrhage with outpatient catheter compared with inpatient dinoprostone. Evidence on misoprostol, hygroscopic dilators, and other outcomes (eg, perinatal mortality and time to vaginal birth) was insufficient.
CONCLUSION
In women with low-risk pregnancies, outpatient cervical ripening with dinoprostone or single-balloon catheters did not increase cesarean deliveries. Although there were no clear differences in harms when comparing outpatient with inpatient cervical ripening, the certainty of evidence is low or insufficient to draw definitive conclusions.

Review
OBJECTIVE
To conduct a systematic review exploring women's experiences, views and understanding of any vaginal examinations during intrapartum care, in any care setting and by any healthcare professional. Intrapartum vaginal examination is deemed both an essential assessment tool and routine intervention during labour. It is an intervention that can cause significant distress, embarrassment, and pain for women, as well as reinforce outdated gender roles. In view of its widespread and frequently reported excessive use, it is important to understand women's views on vaginal examination to inform further research and current practice.
DESIGN
A systematic search and meta-ethnography synthesis informed by Noblit and Hare (1988) and the eMERGe guidance (France et al. 2019) was undertaken. Nine electronic databases were searched systematically using predefined search terms in August 2021, and again in March 2023. Studies meeting the following criteria: English language, qualitative and mixed-method studies, published from 2000 onwards, and relevant to the topic, were eligible for quality appraisal and inclusion.
FINDINGS
Six studies met the inclusion criteria. Three from Turkey, one from Palestine, one from Hong Kong and one from New Zealand. One disconfirming study was identified. Following both a reciprocal and refutational synthesis, four 3rd order constructs were formed, titled: Suffering the examination, Challenging the power dynamic, Cervical-centric labour culture embedded in societal expectations, and Context of care. Finally, a line of argument was arrived at, which brought together and summarised the 3rd order constructs.
KEY CONCLUSIONS AND IMPLICATIONS OF PRACTICE
The dominant biomedical discourse of vaginal examination and cervical dilatation as central to the birthing process does not align with midwifery philosophy or women's embodied experience. Women experience examinations as painful and distressing but tolerate them as they view them as necessary and unavoidable. Factors such as context of care setting, environment, privacy, midwifery care, particularly in a continuity of carer model, have considerable positive affect on women's experience of examinations. Further research into women's experiences of vaginal examination in different care models as well as research into less invasive intrapartum assessment tools that promote physiological processes is urgently required.

Meta-Analysis Review
Maternal and neonatal outcomes with mechanical cervical dilation plus misoprostol compared to misoprostol alone for cervical ripening; a systematic review of literature and metaanalysis.
OBJECTIVE DATA
The aim of the present systematic review was to investigate the efficacy and safety of cervical ripening for the combination of mechanical dilation and misoprostol administration compared with misoprostol alone by evaluating 2 primary outcomes: time to delivery and rate of cesarean delivery.
STUDY
The Medline, EMBASE, and Web-of-Science electronic databases (from conception to end-of-search date December 31, 2018) were searched systematically. Randomized controlled trials that included patients with a singleton viable fetus who underwent induction of labor that required cervical ripening with an unfavorable cervix (Bishop ≤7) were eligible for inclusion.
STUDY APPRAISAL AND SYNTHESIS METHODS
Data were pooled with the use of the random effects and fixed effects model after the assessment for the presence of heterogeneity. Risk of bias for each included study was assessed based on the criteria outlined in the Cochrane Handbook for Systematic Reviews of Interventions.
RESULTS
Eleven trials met the inclusion criteria and included a total of 922 and 947 subjects in the combination and misoprostol-only groups, respectively. There was no difference in the incidence of cesarean delivery between the 2 groups (relative risk, 0.95; 95% confidence interval, 0.80-1.13). The combination of mechanical dilation and misoprostol resulted in overall shorter time to delivery (mean difference, -3.65 hours; 95% confidence interval, 5.23 to -2.07), shorter time to vaginal delivery (mean difference, -4.53 hours; 95% confidence interval, -5.79 to -3.27), lower risk of neonatal intensive care unit admission (relative risk, 0.71; 95% confidence interval, 0.53-0.96), meconium-stained fluid (relative risk, 0.62; 95% confidence interval, 0.43-0.90), tachysystole with fetal heart trace changes (relative risk, 0.53; 95% confidence interval, 0.30-0.94), and terbutaline use (relative risk, 0.63; 95% confidence interval, 0.47-0.85) compared with the use of misoprostol alone. Risk of endometritis (relative risk, 1.07; 95% confidence interval, 0.43-2.61) and chorioamnionitis (relative risk, 1.58; 95% confidence interval, 0.88-2.84) was comparable between the 2 groups.
CONCLUSION
The combination of mechanical cervical dilation with misoprostol for cervical ripening is associated with a shorter time to delivery, a similar rate of cesarean delivery, and a lower incidence of neonatal intensive care unit admission compared with the use of misoprostol alone.

Meta-Analysis
BACKGROUND
The rates of successful vaginal birth after previous cesarean section (VBAC) have been increasing with minimal complication. Successful vaginal birth after cesarean section improves maternal and fetal outcomes by shortening the length of hospital stay, avoiding abdominal surgery, decreasing the risk of infections and hemorrhage, and decreasing injury of the bladder and bowel. Despite a few single studies stating different predictors of successful VBAC, there is a lack of nationwide data to show the determinants of successful VBAC. Thus, this meta-analysis aimed to determine the predictors of successful VBAC in Ethiopia.
METHODS
A systematic literature search was performed from PubMed, Web of Sciences, EMBASE, CINAHL, and Google scholar until July 25, 2022. The quality of included studies was evaluated using the Joanna Briggs Institute (JBI) critical appraisal checklist. The analysis was executed using Stata 14 statistical software. Heterogeneity was evaluated statistically using Cochran's Q-statistic and quantified by the I value. A random-effects model was used to estimate the determinants of successful vaginal birth after a cesarean section if substantial heterogeneity was detected across included studies; otherwise, a fixed-effects model was used.
RESULTS
Women living in rural residence (AOR: 2.14; 95% CI: 1.01, 4.52), history of previous spontaneous vaginal delivery (AOR: 2.92; 95% CI: 2.02, 4.23), previous successful vaginal birth after previous cesarean section (AOR: 5.29; 95% CI: 2.20, 12.69), history of stillbirth (AOR: 1.57; 95% CI: 1.20, 2.04), cervical dilation of ≥ 4 cm at admission (AOR: 2.14; 95% CI: 1.27, 3.61), spontaneous ruptured membranes at admission (AOR: 1.32; 95% CI: 1.17, 1.48) were independent determinants of successful vaginal birth after previous cesarean section.
CONCLUSION
The results of this meta-analysis showed that successful VBAC was influenced by past and present obstetric conditions and other predictors. Thus, it is recommended that obstetric care providers should emphasize those factors that lead to successful vaginal birth during counseling and optimal selection of women for the trial of labour after cesarean section.

Meta-Analysis Review
BACKGROUND
Pelvic organ prolapse (POP) affects as many as 50% of parous women, with 14% to 19% of women undergoing a surgical correction. Although surgery for the treatment of POP is common, limited supportive data can be found in the literature regarding the preoperative and postoperative interventions related to these procedures. The main goal of perioperative interventions is to reduce the rate of adverse events while improving women's outcomes following surgical intervention for prolapse. A broad spectrum of perioperative interventions are available, and although the benefits of interventions such as prophylactic antibiotics before abdominal surgery are well established, others are unique to women undergoing POP surgeries and as such need to be investigated separately.
OBJECTIVES
The aim of this review is to compare the safety and effectiveness of a range of perioperative interventions versus other interventions or no intervention (control group) at the time of surgery for pelvic organ prolapse.
SEARCH METHODS
We searched the Cochrane Incontinence Group Specialised Register, which contains trials identified from the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, MEDLINE In Process, ClinicalTrials.gov, WHO ICTRP, handsearching of journals and conference proceedings (searched 30 November 2017), and reference lists of relevant articles. We also contacted researchers in the field.
SELECTION CRITERIA
We included randomised controlled trials (RCTs) of women undergoing surgical treatment for symptomatic pelvic organ prolapse that compared a perioperative intervention related to pelvic organ prolapse surgery versus no treatment or another intervention.
DATA COLLECTION AND ANALYSIS
We used standard methodological procedures recommended by Cochrane. Our primary outcomes were objective failure at any site and subjective postoperative prolapse symptoms. We also measured adverse effects, focusing on intraoperative blood loss and blood transfusion, intraoperative ureteral injury, and postoperative urinary tract infection.
MAIN RESULTS
We included 15 RCTs that compared eight different interventions versus no treatment for 1992 women in five countries. Most interventions were assessed by only one RCT with evidence quality ranging from very low to moderate. The main limitation was imprecision, associated with small sample sizes and low event rates.Pelvic floor muscle training (PFMT) compared with no treatment (three RCTs) - peri-operative intervention The simplest of the PFMT programmes required women to attend six perioperative consultations in the three months surrounding prolapse surgery. Trial results provided no clear evidence of a difference between groups in objective failure at any site at 12 to 24 months (odds ratio (OR) 0.93, 95% confidence interval (CI) 0.56 to 1.54; two RCTs, 327 women; moderate-quality evidence). With respect to awareness of prolapse, findings were inconsistent. One RCT found no evidence of a difference between groups at 24 months (OR 1.07, 95% CI 0.61 to 1.87; one RCT, 305 women; low-quality evidence), and a second small RCT reported symptom reduction from the Pelvic Organ Prolapse Symptom Questionnaire completed by the intervention group at 12 months (mean difference (MD) -3.90, 95% CI -6.11 to -1.69; one RCT, 27 women; low-quality evidence). Researchers found no clear differences between groups at 24-month follow-up in rates of repeat surgery (or pessary) for prolapse (OR 1.92, 95% CI 0.74 to 5.02; one RCT, 316 women; low-quality evidence).Other interventionsSingle RCTs evaluated the following interventions: preoperative guided imagery (N = 44); injection of vasoconstrictor agent at commencement of vaginal prolapse surgery (N = 76); ureteral stent placement during uterosacral ligament suspension (N = 91); vaginal pack (N = 116); prophylactic antibiotics for women requiring postoperative urinary catheterisation (N = 159); and postoperative vaginal dilators (N = 60).Two RCTs evaluated bowel preparation (N = 298), and four RCTs assessed the method and timing of postoperative catheterisation (N = 514) - all in different comparisons.None of these studies reported our primary review outcomes. One study reported intraoperative blood loss and suggested that vaginal injection of vasoconstrictors at commencement of surgery may reduce blood loss by a mean of about 30 mL. Another study reported intraoperative ureteral injury and found no clear evidence that ureteral stent placement reduces ureteral injury. Three RCTs reported postoperative urinary tract infection and found no conclusive evidence that rates of urinary tract infection were influenced by use of a vaginal pack, prophylactic antibiotics, or vaginal dilators. Other studies did not report these outcomes.
AUTHORS' CONCLUSIONS
There was a paucity of data about perioperative interventions in pelvic organ prolapse surgery. A structured programme of pelvic floor muscle training before and after prolapse surgery did not consistently demonstrate any benefit for the intervention; however, this finding is based on the results of two small studies. With regard to other interventions (preoperative bowel preparation and injection of vasoconstrictor agent, ureteral stent placement during uterosacral ligament suspension, postoperative vaginal pack insertion, use of vaginal dilators, prophylactic antibiotics for postoperative catheter care), we found no evidence regarding rates of recurrent prolapse and no clear evidence that these interventions were associated with clinically meaningful reductions in adverse effects, such as intraoperative or postoperative blood transfusion, intraoperative ureteral injury, or postoperative urinary tract infection.

BACKGROUND
Vaginal birth after caesarean section (VBAC) is an alternative to a caesarean section (CS) in the absence of repeat or new indications for primary CS. There is a knowledge gap regarding the trend and successful VBAC in Ethiopia. Therefore this systematic review and meta-analysis aimed to assess the trend, pooled prevalence of successful VBAC and its predictors in Ethiopia.
METHODS
Electronic databases (SCOPUS, CINAHL, Embase, PubMed and Web of Science), Google Scholar and lists of references were used to search works of literature in Ethiopia. Stata version 14 was used for analysis and the odds ratios of the outcome variable were determined using the random effects model. Heterogeneity among the studies was assessed by computing values for I2 and p-values. Also, sensitivity analyses and funnel plots were done to assess the stability of pooled values to outliers and publication bias, respectively.
RESULTS
A total of 12 studies with a sample size of 2080 were included in this study. The overall success rate of VBAC was 52% (95% confidence interval 42 to 65). Cervical dilatation ≥4 cm at admission, having a prior successful vaginal delivery and VBAC were the predictors of successful VBAC.
CONCLUSIONS
Meta-analyses and sensitivity analyses showed the stability of the pooled odds ratios and the funnel plots did not show publication bias. The pooled prevalence of successful VBAC was relatively low compared with existing evidence. However, the rate was increasing over the last 3 decades, which implies it needs more strengthening and focus to decrease maternal morbidity and mortality by CS complications. Promoting VBAC by emphasizing factors favourable for its success during counselling mothers who previously delivered by CS to enhance the prevalence of VBAC.

Meta-Analysis Review
BACKGROUND
Hysteroscopy is an operation in which the gynaecologist examines the uterine cavity using a small telescopic instrument (hysteroscope) inserted via the vagina and the cervix. Almost 50% of hysteroscopic complications are related to difficulty with cervical entry. Potential complications include cervical tears, creation of a false passage, perforation, bleeding, or simply difficulty in entering the internal os (between the cervix and the uterus) with the hysteroscope. These complications may possibly be reduced with adequate preparation of the cervix (cervical ripening) prior to hysteroscopy. Cervical ripening agents include oral or vaginal prostaglandin, which can be synthetic (e.g misoprostol) or natural (e.g. dinoprostone) and vaginal osmotic dilators, which can be naturally occurring (e.g. laminaria) or synthetic.
OBJECTIVES
To determine whether preoperative cervical preparation facilitates cervical dilatation and reduces the complications of operative hysteroscopy in women undergoing the procedure for any condition.
SEARCH METHODS
In August 2014 we searched sources including the Menstrual Disorders and Subfertility Group (MDSG) Trials Register, Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, PsycINFO, CINAHL, ClinicalTrials.gov and reference lists of relevant articles. We searched for published and unpublished studies in any language.
SELECTION CRITERIA
Two review authors independently selected randomised controlled trials (RCTs) of cervical ripening agents used before operative hysteroscopy in pre- and postmenopausal women. Cervical ripening agents could be compared to each other, placebo or no treatment.
DATA COLLECTION AND ANALYSIS
Data extraction and quality assessment were conducted independently by two review authors. The primary review outcomes were effectiveness of cervical dilatation (defined as the proportion of women requiring mechanical cervical dilatation) and intraoperative complications. Secondary outcomes were mean time required to dilate the cervix, preoperative pain, cervical width, abandonment of the procedure, side effects of dilating agents and duration of surgery. We calculated odds ratios (ORs) for dichotomous outcomes and mean differences (MDs) for continuous outcomes, with 95% confidence intervals ( CIs). Data were statistically pooled where appropriate. Heterogeneity was assessed using the I(2) statistic. The overall quality of the evidence was assessed using GRADE methods.
MAIN RESULTS
Nineteen RCTs with a total of 1870 participants were included. They compared misoprostol with no treatment or placebo, dinoprostone or osmotic dilators.Misoprostol was more effective for cervical dilatation than placebo or no intervention, with fewer women requiring mechanical dilatation (OR 0.08, 95% CI 0.04 to 0.16, five RCTs, 441 participants, I(2)=0%, moderate quality evidence). This suggests that in a population in which 80% of women undergoing hysteroscopy require mechanical dilatation without use of preoperative ripening agents, use of misoprostol will reduce the need for mechanical dilatation to between 14% and 39%. Misoprostol was associated with fewer intraoperative complications (OR 0.37, 95% CI 0.18 to 0.77, 12 RCTs, 901 participants, I(2)=0%, moderate quality evidence). This suggests that in a population in which 3% of women undergoing hysteroscopy experience intraoperative complications without use of preoperative ripening agents, use of misoprostol will reduce the risk of complications to 2% or less.When specific complications were considered, the misoprostol group had a lower rate of cervical laceration or tearing (OR 0.25, 95% CI 0.11 to 0.57, nine RCTS, 669 women, I(2)=0%, moderate quality evidence) or false track formation (OR 0.34, 95% CI 0.12 to 0.97, seven RCTs, 560 participants, I(2)=0%, moderate quality evidence). There was no evidence of a difference between the groups in rates of uterine perforation (0.42, 95% CI 0.13 to 1.38, seven RCTs, 455 participants, I(2)=0%, low quality evidence) or uterine bleeding (OR 0.51, 95% CI 0.10 to 2.49, four RCTs, 340 participants, I(2)=0%, low quality evidence). Some treatment side effects (mild abdominal pain, vaginal bleeding, and increased body temperature) were more common in the misoprostol group.Compared with dinoprostone, misoprostol was associated with more effective cervical dilatation, with fewer women requiring mechanical dilatation (OR 0.58; 95% CI 0.34 to 0.98; one RCT, 310 participants, low quality evidence) and with fewer intraoperative complications (OR 0.32; 95% CI 0.12 to 0.83, one RCT, 310 participants, low quality evidence). However treatment side effects were more common in the misoprostol arm.Compared to osmotic dilatation (laminaria), misoprostol was associated with less effective cervical dilatation, with more women in the misoprostol group requiring mechanical dilatation (OR 5.96, 95% CI 2.61 to 13.59, one RCT, 110 participants, low quality evidence). There was no evidence of a difference between misoprostol and osmotic dilators in intraoperative complication rates (OR 5.14, 95% CI 0.24 to 109.01, three RCTs, 354 participants, low quality evidence), with only two events reported altogether.The overall quality of the evidence ranged from low to moderate. The main limitations in the evidence were imprecision and poor reporting of study methods.
AUTHORS' CONCLUSIONS
There is moderate quality evidence that use of misoprostol for preoperative ripening of the cervix before operative hysteroscopy is more effective than placebo or no treatment and is associated with fewer intraoperative complications such as lacerations and false tracks. However misoprostol is associated with more side effects, including preoperative pain and vaginal bleeding. There is low quality evidence to suggest that misoprostol has fewer intraoperative complications and is more effective than dinoprostone.There is also low quality evidence to suggest that laminaria may be more effective than misoprostol, with uncertain effects for complication rates. However the possible benefits of laminaria need to be weighed against the inconvenience of its insertion and retention for one to two days.

Review
Female sexual dysfunction occurs frequently in midlife breast cancer survivors (BCS) and encompasses problems with sexual desire, interest, arousal, orgasm and genitopelvic pain. Although common, sexual problems are under-diagnosed and under-treated in BCS. The objective of this review was to assess primary studies that intervene on sexual dysfunction in BCS. In February 2015, PubMed, SCOPUS, CINAHL, COCHRANE and Web of Science databases were systematically searched for randomized controlled clinical trials (RCTs) of vaginal (lubricants, moisturizers, estrogens, dehydroepiandrosterone [DHEA], testosterone, vibrators, dilators), systemic (androgens, anti-depressants, flibanserin, ospemifene), physical therapy (physical activity, pelvic floor training), counseling and educational interventions on sexual function in BCS. Observational studies of vaginal interventions were also included due to the paucity of RCTs. The search yielded 1414 studies, 34 of which met inclusion criteria. Both interventions and outcomes, measured by 31 different sexual function scales, were heterogeneous, and therefore data were not pooled. The review found that regular and prolonged use of vaginal moisturizers was effective in improving vaginal dryness, dyspareunia, and sexual satisfaction. Educational and counseling interventions targeting sexual dysfunction showed consistent improvement in various aspects of sexual health. No consistent improvements in sexual health were observed with physical activity, transdermal testosterone or hot flash interventions. There was a lack of BCS-specific data on vaginal lubricants, vibrators, dilators, pelvic floor therapy, flibanserin or ospemifene. Overall, the quality of evidence for these studies was moderate to very low. Because each of the interventions with BCS data had limited efficacy, clinical trials to test novel interventions are needed to provide evidence-based clinical recommendations and improve sexual function in BCS.

Meta-Analysis Review
Labor pain (LP), as a physiological process, is known as one of the most severe pains. Aromatherapy is one of the methods to reduce LP in the first phase of labor. It is an important approach for enjoyable birth and decreases the severity of pain in today's society. Accordingly, this study aimed to systematically review the relieving effect of aromatherapy in LP and Apgar score. We used international databases such as EMBASE, Web of Science, Scopus, Google Scholar, PubMed, Cochrane Library, ProQuest, and clinicaltrials.gov to conduct a systematic search for all relevant articles. Cochran's Q-test and I statistic were applied to assess heterogeneity, a random-effects model was used to estimate the unstandardized mean difference (UMD), and a meta-regression method was utilized to investigate the factors affecting heterogeneity between studies. A total of 27 studies were included in the meta-analysis (sample size: 2,566). Overall, aromatherapy leads to relieving LP during delivery (UMD: 1.75; 95% CI: 1.13-2.37). Based on cervix dilation, aromatherapy significantly affects LP when cervix dilation is 8-10 cm (UMD: 6.18; 95% CI: 4.51-7.85) and 0-4 cm (UMD: 5.31; 95% CI: 3.74-6.87); but it had no effects on 1- and 5-min Apgar scores. No publication bias was observed (P=0.113). Mother's age, publication year, sample size, and cervix dilation had no significant effects on heterogeneity (P>0.05). Aromatherapy had a positive impact on relieving LP, and the greatest and least effect was witnessed in dilatation of 8-10 cm and 0-4 cm, respectively. Moreover, it had no effects on 1- and 5-min Apgar scores.
