Meta-Analysis
BACKGROUND
More than 10 years have elapsed since human papillomavirus (HPV) vaccination was implemented. We did a systematic review and meta-analysis of the population-level impact of vaccinating girls and women against human papillomavirus on HPV infections, anogenital wart diagnoses, and cervical intraepithelial neoplasia grade 2+ (CIN2+) to summarise the most recent evidence about the effectiveness of HPV vaccines in real-world settings and to quantify the impact of multiple age-cohort vaccination.
METHODS
In this updated systematic review and meta-analysis, we used the same search strategy as in our previous paper. We searched MEDLINE and Embase for studies published between Feb 1, 2014, and Oct 11, 2018. Studies were eligible if they compared the frequency (prevalence or incidence) of at least one HPV-related endpoint (genital HPV infections, anogenital wart diagnoses, or histologically confirmed CIN2+) between pre-vaccination and post-vaccination periods among the general population and if they used the same population sources and recruitment methods before and after vaccination. Our primary assessment was the relative risk (RR) comparing the frequency (prevalence or incidence) of HPV-related endpoints between the pre-vaccination and post-vaccination periods. We stratified all analyses by sex, age, and years since introduction of HPV vaccination. We used random-effects models to estimate pooled relative risks.
FINDINGS
We identified 1702 potentially eligible articles for this systematic review and meta-analysis, and included 65 articles in 14 high-income countries: 23 for HPV infection, 29 for anogenital warts, and 13 for CIN2+. After 5-8 years of vaccination, the prevalence of HPV 16 and 18 decreased significantly by 83% (RR 0·17, 95% CI 0·11-0·25) among girls aged 13-19 years, and decreased significantly by 66% (RR 0·34, 95% CI 0·23-0·49) among women aged 20-24 years. The prevalence of HPV 31, 33, and 45 decreased significantly by 54% (RR 0·46, 95% CI 0·33-0·66) among girls aged 13-19 years. Anogenital wart diagnoses decreased significantly by 67% (RR 0·33, 95% CI 0·24-0·46) among girls aged 15-19 years, decreased significantly by 54% (RR 0·46, 95% CI 0.36-0.60) among women aged 20-24 years, and decreased significantly by 31% (RR 0·69, 95% CI 0·53-0·89) among women aged 25-29 years. Among boys aged 15-19 years anogenital wart diagnoses decreased significantly by 48% (RR 0·52, 95% CI 0·37-0·75) and among men aged 20-24 years they decreased significantly by 32% (RR 0·68, 95% CI 0·47-0·98). After 5-9 years of vaccination, CIN2+ decreased significantly by 51% (RR 0·49, 95% CI 0·42-0·58) among screened girls aged 15-19 years and decreased significantly by 31% (RR 0·69, 95% CI 0·57-0·84) among women aged 20-24 years.
INTERPRETATION
This updated systematic review and meta-analysis includes data from 60 million individuals and up to 8 years of post-vaccination follow-up. Our results show compelling evidence of the substantial impact of HPV vaccination programmes on HPV infections and CIN2+ among girls and women, and on anogenital warts diagnoses among girls, women, boys, and men. Additionally, programmes with multi-cohort vaccination and high vaccination coverage had a greater direct impact and herd effects.

Meta-Analysis
BACKGROUND AND PURPOSE
Optimizing speech and language therapy (SLT) regimens for maximal aphasia recovery is a clinical research priority. We examined associations between SLT intensity (hours/week), dosage (total hours), frequency (days/week), duration (weeks), delivery (face to face, computer supported, individual tailoring, and home practice), content, and language outcomes for people with aphasia.
METHODS
Databases including MEDLINE and Embase were searched (inception to September 2015). Published, unpublished, and emerging trials including SLT and ≥10 individual participant data on aphasia, language outcomes, and time post-onset were selected. Patient-level data on stroke, language, SLT, and trial risk of bias were independently extracted. Outcome measurement scores were standardized. A statistical inferencing, one-stage, random effects, network meta-analysis approach filtered individual participant data into an optimal model examining SLT regimen for overall language, auditory comprehension, naming, and functional communication pre-post intervention gains, adjusting for a priori-defined covariates (age, sex, time poststroke, and baseline aphasia severity), reporting estimates of mean change scores (95% CI).
RESULTS
Data from 959 individual participant data (25 trials) were included. Greatest gains in overall language and comprehension were associated with >20 to 50 hours SLT dosage (18.37 [10.58-26.16] Western Aphasia Battery-Aphasia Quotient; 5.23 [1.51-8.95] Aachen Aphasia Test-Token Test). Greatest clinical overall language, functional communication, and comprehension gains were associated with 2 to 4 and 9+ SLT hours/week. Greatest clinical gains were associated with frequent SLT for overall language, functional communication (3-5+ days/week), and comprehension (4-5 days/week). Evidence of comprehension gains was absent for SLT ≤20 hours, <3 hours/week, and ≤3 days/week. Mixed receptive-expressive therapy, functionally tailored, with prescribed home practice was associated with the greatest overall gains. Relative variance was <30%. Risk of trial bias was low to moderate; low for meta-biases.
CONCLUSIONS
Greatest language recovery was associated with frequent, functionally tailored, receptive-expressive SLT, with prescribed home practice at a greater intensity and duration than reports of usual clinical services internationally. These exploratory findings suggest critical therapeutic ranges, informing hypothesis-testing trials and tailoring of clinical services.

Meta-Analysis
BACKGROUND
Umbilical cord clamping strategies at preterm birth have the potential to affect important health outcomes. The aim of this study was to compare the effectiveness of deferred cord clamping, umbilical cord milking, and immediate cord clamping in reducing neonatal mortality and morbidity at preterm birth.
METHODS
We conducted a systematic review and individual participant data meta-analysis. We searched medical databases and trial registries (from database inception until Feb 24, 2022; updated June 6, 2023) for randomised controlled trials comparing deferred (also known as delayed) cord clamping, cord milking, and immediate cord clamping for preterm births (<37 weeks' gestation). Quasi-randomised or cluster-randomised trials were excluded. Authors of eligible studies were invited to join the iCOMP collaboration and share individual participant data. All data were checked, harmonised, re-coded, and assessed for risk of bias following prespecified criteria. The primary outcome was death before hospital discharge. We performed intention-to-treat one-stage individual participant data meta-analyses accounting for heterogeneity to examine treatment effects overall and in prespecified subgroup analyses. Certainty of evidence was assessed with Grading of Recommendations Assessment, Development, and Evaluation. This study is registered with PROSPERO, CRD42019136640.
FINDINGS
We identified 2369 records, of which 48 randomised trials provided individual participant data and were eligible for our primary analysis. We included individual participant data on 6367 infants (3303 [55%] male, 2667 [45%] female, two intersex, and 395 missing data). Deferred cord clamping, compared with immediate cord clamping, reduced death before discharge (odds ratio [OR] 0·68 [95% CI 0·51-0·91], high-certainty evidence, 20 studies, n=3260, 232 deaths). For umbilical cord milking compared with immediate cord clamping, no clear evidence was found of a difference in death before discharge (OR 0·73 [0·44-1·20], low certainty, 18 studies, n=1561, 74 deaths). Similarly, for umbilical cord milking compared with deferred cord clamping, no clear evidence was found of a difference in death before discharge (0·95 [0·59-1·53], low certainty, 12 studies, n=1303, 93 deaths). We found no evidence of subgroup differences for the primary outcome, including by gestational age, type of delivery, multiple birth, study year, and perinatal mortality.
INTERPRETATION
This study provides high-certainty evidence that deferred cord clamping, compared with immediate cord clamping, reduces death before discharge in preterm infants. This effect appears to be consistent across several participant-level and trial-level subgroups. These results will inform international treatment recommendations.

Meta-Analysis
Short, medium, and long deferral of umbilical cord clamping compared with umbilical cord milking and immediate clamping at preterm birth: a systematic review and network meta-analysis with individual participant data.
BACKGROUND
Deferred (also known as delayed) cord clamping can improve survival of infants born preterm (before 37 weeks of gestation), but the optimal duration of deferral remains unclear. We conducted a systematic review and individual participant data network meta-analysis with the aim of comparing the effectiveness of umbilical cord clamping strategies with different timings of clamping or with cord milking for preterm infants.
METHODS
We searched medical databases and trial registries from inception until Feb 24, 2022 (updated June 6, 2023) for randomised controlled trials comparing cord clamping strategies for preterm infants. Individual participant data were harmonised and assessed for risk of bias and quality. Interventions were grouped into immediate clamping, short deferral (≥15 s to <45 s), medium deferral (≥45 s to <120 s), long deferral (≥120 s), and intact cord milking. The primary outcome was death before hospital discharge. We calculated one-stage, intention-to-treat Bayesian random-effects individual participant data network meta-analysis. This study was registered with PROSPERO, CRD42019136640.
FINDINGS
We included individual participant data from 47 trials with 6094 participants. Of all interventions, long deferral reduced death before discharge the most (compared with immediate clamping; odds ratio 0·31 [95% credibility interval] 0·11-0·80; moderate certainty). The risk of bias was low for 10 (33%) of 30 trials, 14 (47%) had some concerns, and 6 (20%) were rated as having a high risk of bias. Heterogeneity was low, with no indication of inconsistency.
INTERPRETATION
This study found that long deferral of clamping leads to reduced odds of death before discharge in preterm infants. In infants assessed as requiring immediate resuscitation, this finding might only be generalisable if there are provisions for such care with the cord intact. These results are based on thoroughly cleaned and checked individual participant data and can inform future guidelines and practice.

Meta-Analysis Review
BACKGROUND
Diverticula of the appendix (DA) are infrequent and their clinical implications are often overlooked. Several studies have found a significantly increased prevalence of neoplasms in appendiceal specimens with diverticula. Despite the potential clinical implications, there is a paucity of literature. A systematic review and meta-analysis was performed to evaluate the prevalence of DA and its association with neoplasia.
METHODS
A systematic search of literature (Cochrane, EMBASE, PubMed and Medline) reporting the prevalence of DA and association with neoplasia was performed in November 2019. Relevant articles were assessed in accordance with the PRISMA guidelines. Risk of bias assessment was carried out using modified Newcastle-Ottawa scale. Meta-analysis with risk ratio and random-effects model was performed using RevMan.
RESULTS
The initial search identified 1122 potential articles of which 11 were appropriate for quantitative analysis. The prevalence rate of DA was 1.74%. The mean age of patients with DA and those without DA was 41.2 and 33.9 years, respectively. The ratio of male to female was 1.8:1. The prevalence of neoplasia in specimens without DA versus those with DA was 1.28% and 26.94%, respectively. Only four studies addressed the prevalence of locoregional neoplasia in the setting of DA compared to control. Meta-analysis with random-effects model demonstrated that pooled risk ratio was 25.46 (95% confidence interval 12.77-50.75, P < 0.00001).
CONCLUSION
The strong association with neoplasia in this meta-analysis reinforces the clinical significance of DA. Surgeons, pathologists and radiologists should be mindful of this uncommon pathology and consider individualized patient management, until further evidence can direct clinical guidelines for the management of patients with DA.

BMJ (Clinical Research Ed.) Dec 2023What is the comparative effectiveness of available therapies for chronic pain associated with temporomandibular disorders (TMD)? (Meta-Analysis)
Meta-Analysis
CLINICAL QUESTION
What is the comparative effectiveness of available therapies for chronic pain associated with temporomandibular disorders (TMD)?
CURRENT PRACTICE
TMD are the second most common musculoskeletal chronic pain disorder after low back pain, affecting 6-9% of adults globally. TMD are associated with pain affecting the jaw and associated structures and may present with headaches, earache, clicking, popping, or crackling sounds in the temporomandibular joint, and impaired mandibular function. Current clinical practice guidelines are largely consensus-based and provide inconsistent recommendations.
RECOMMENDATIONS
For patients living with chronic pain (≥3 months) associated with TMD, and compared with placebo or sham procedures, the guideline panel issued: (1) strong recommendations in favour of cognitive behavioural therapy (CBT) with or without biofeedback or relaxation therapy, therapist-assisted mobilisation, manual trigger point therapy, supervised postural exercise, supervised jaw exercise and stretching with or without manual trigger point therapy, and usual care (such as home exercises, stretching, reassurance, and education); (2) conditional recommendations in favour of manipulation, supervised jaw exercise with mobilisation, CBT with non-steroidal anti-inflammatory drugs (NSAIDS), manipulation with postural exercise, and acupuncture; (3) conditional recommendations against reversible occlusal splints (alone or in combination with other interventions), arthrocentesis (alone or in combination with other interventions), cartilage supplement with or without hyaluronic acid injection, low level laser therapy (alone or in combination with other interventions), transcutaneous electrical nerve stimulation, gabapentin, botulinum toxin injection, hyaluronic acid injection, relaxation therapy, trigger point injection, acetaminophen (with or without muscle relaxants or NSAIDS), topical capsaicin, biofeedback, corticosteroid injection (with or without NSAIDS), benzodiazepines, and β blockers; and (4) strong recommendations against irreversible oral splints, discectomy, and NSAIDS with opioids.
HOW THIS GUIDELINE WAS CREATED
An international guideline development panel including patients, clinicians with content expertise, and methodologists produced these recommendations in adherence with standards for trustworthy guidelines using the GRADE approach. The MAGIC Evidence Ecosystem Foundation (MAGIC) provided methodological support. The panel approached the formulation of recommendations from the perspective of patients, rather than a population or health system perspective.
THE EVIDENCE
Recommendations are informed by a linked systematic review and network meta-analysis summarising the current body of evidence for benefits and harms of conservative, pharmacologic, and invasive interventions for chronic pain secondary to TMD.
UNDERSTANDING THE RECOMMENDATION
These recommendations apply to patients living with chronic pain (≥3 months duration) associated with TMD as a group of conditions, and do not apply to the management of acute TMD pain. When considering management options, clinicians and patients should first consider strongly recommended interventions, then those conditionally recommended in favour, then conditionally against. In doing so, shared decision making is essential to ensure patients make choices that reflect their values and preference, availability of interventions, and what they may have already tried. Further research is warranted and may alter recommendations in the future.

Meta-Analysis
CLINICAL QUESTION
What are the benefits and harms of sodium-glucose cotransporter 2 (SGLT-2) inhibitors and glucagon-like peptide 1 (GLP-1) receptor agonists when added to usual care (lifestyle interventions and/or other diabetes drugs) in adults with type 2 diabetes at different risk for cardiovascular and kidney outcomes?
CURRENT PRACTICE
Clinical decisions about treatment of type 2 diabetes have been led by glycaemic control for decades. SGLT-2 inhibitors and GLP-1 receptor agonists are traditionally used in people with elevated glucose level after metformin treatment. This has changed through trials demonstrating atherosclerotic cardiovascular disease (CVD) and chronic kidney disease (CKD) benefits independent of medications' glucose-lowering potential.
RECOMMENDATIONS
The guideline panel issued risk-stratified recommendations concerning the use of SGLT-2 inhibitors or GLP-1 receptor agonists in adults with type 2 diabetes• Three or fewer cardiovascular risk factors without established CVD or CKD: Weak recommendation against starting SGLT-2 inhibitors or GLP-1 receptor agonists.• More than three cardiovascular risk factors without established CVD or CKD: Weak recommendation for starting SGLT-2 inhibitors and weak against starting GLP-1 receptor agonists.• Established CVD or CKD: Weak recommendation for starting SGLT-2 inhibitors and GLP-1 receptor agonists.• Established CVD and CKD: Strong recommendation for starting SGLT-2 inhibitors and weak recommendation for starting GLP-1 receptor agonists.• For those committed to further reducing their risk for CVD and CKD outcomes: Weak recommendation for starting SGLT-2 inhibitors rather than GLP-1 receptor agonists.
HOW THIS GUIDELINE WAS CREATED
An international panel including patients, clinicians, and methodologists created these recommendations following standards for trustworthy guidelines and using the GRADE approach. The panel applied an individual patient perspective.
THE EVIDENCE
A linked systematic review and network meta-analysis (764 randomised trials included 421 346 participants) of benefits and harms found that SGLT-2 inhibitors and GLP-1 receptor agonists generally reduce overall death, and incidence of myocardial infarctions, and end-stage kidney disease or kidney failure (moderate to high certainty evidence). These medications exert different effects on stroke, hospitalisations for heart failure, and key adverse events in different subgroups. Absolute effects of benefit varied widely based on patients' individual risk (for example, from five fewer deaths in the lowest risk to 48 fewer deaths in the highest risk, for 1000 patients treated over five years). A prognosis review identified 14 eligible risk prediction models, one of which (RECODe) informed most baseline risk estimates in evidence summaries to underpin the risk-stratified recommendations. Concerning patients' values and preferences, the recommendations were supported by evidence from a systematic review of published literature, a patient focus group study, a practical issues summary, and a guideline panel survey.
UNDERSTANDING THE RECOMMENDATION
We stratified the recommendations by the levels of risk for CVD and CKD and systematically considered the balance of benefits, harms, other considerations, and practical issues for each risk group. The strong recommendation for SGLT-2 inhibitors in patients with CVD and CKD reflects what the panel considered to be a clear benefit. For all other adults with type 2 diabetes, the weak recommendations reflect what the panel considered to be a finer balance between benefits, harms, and burdens of treatment options. Clinicians using the guideline can identify their patient's individual risk for cardiovascular and kidney outcomes using credible risk calculators such as RECODe. Interactive evidence summaries and decision aids may support well informed treatment choices, including shared decision making.

Journal of Obstetrics and Gynaecology... Apr 2021To compare success and complication rates of apical suspension procedures for the surgical management of symptomatic uterine or vaginal vault prolapse. (Meta-Analysis)
Meta-Analysis
OBJECTIVE
To compare success and complication rates of apical suspension procedures for the surgical management of symptomatic uterine or vaginal vault prolapse.
TARGET POPULATION
Women with symptomatic uterine or vaginal vault prolapse seeking surgical correction.
OPTIONS
Interventions included abdominal apical reconstructive repairs (sacrocolpopexy, sacrohysteropexy, or uterosacral hysteropexy) via open, laparoscopic, or robotic approaches; vaginal apical reconstructive repairs (vault suspensions or hysteropexy, sacrospinous, uterosacral, iliococcygeus, McCall's, or Manchester types); and vaginal obliterative procedures (with or without uterus in situ). Individual procedures or broad categories of procedures were compared: (1) vaginal versus abdominal routes for reconstruction, (2) abdominal procedures for reconstruction, (3) vaginal procedures for reconstruction, (4) hysterectomy and suspension versus hysteropexy for reconstruction, and (5) reconstructive versus obliterative options.
OUTCOMES
The Urogynaecology Committee selected outcomes of interest: objective failure (obtained via validated pelvic organ prolapse [POP] quantification systems and defined as overall objective failure as well as failure rate by compartment); subjective failure (recurrence of bulge symptoms determined subjectively, with or without use of a validated questionnaire); reoperation for POP recurrence; complications of postoperative lower urinary tract symptoms (de novo or postoperative stress urinary incontinence; reoperation for persistent, recurrent, or de novo stress urinary incontinence; urge urinary incontinence; and voiding dysfunction); perioperatively recognized urinary tract injury (bladder or ureter); other complications (mesh exposure, defined as mesh being visible and exposed in the vagina, and non-sexual pelvic pain); and sexual function (de novo dyspareunia and sexual function score according to a validated questionnaire).
BENEFITS, HARMS, AND COSTS
This guideline will benefit patients seeking surgical correction of apical POP by improving counselling on surgical treatment options and possible outcomes. It will also benefit surgical providers by improving their knowledge of various surgical approaches. Data presented could be used to develop frameworks and tools for shared decision-making.
EVIDENCE
We searched Medline, the Cochrane Central Register of Controlled Trials (CENTRAL), and Embase from 2002 to 2019. The search included multiple terms for apical POP surgical procedures, approaches, and complications. We excluded POP repairs using transvaginal mesh and studies that compared procedures without apical suspension. We included randomized controlled trials and prospective or retrospective comparative studies. We limited language of publication to English and French and accessibility to full text. A systematic review and meta-analysis was performed.
VALIDATION METHODS
The authors rated the quality of evidence and strength of recommendations using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. See online Appendix A (Tables A1 for definitions and A2 for interpretations of strong and weak recommendations).
INTENDED USERS
Gynaecologists, urologists, urogynaecologists, and other health care providers who assess, counsel, and care for women with POP.
SUMMARY STATEMENTS
All statements refer to correction of apical vaginal prolapse in the short and medium term (up to 5 years), except when otherwise specified.

Review
INTRODUCTION
Appendicitis is an inflammation of the appendix that may lead to an abscess, ileus, peritonitis, or death if untreated. Appendicitis is the most common abdominal surgical emergency. The current standard treatment of uncomplicated appendicitis is usually surgery, but there has been increasing evidence published on the use of antibiotics.
METHODS AND OUTCOMES
We conducted a systematic review and aimed to answer the following clinical question: What are the effects of surgery compared with antibiotics for acute appendicitis? We searched: Medline, Embase, The Cochrane Library, and other important databases up to May 2014 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA).
RESULTS
We found four studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions.
CONCLUSIONS
In this systematic review we present information relating to the effectiveness and safety of surgery (including laparoscopic and open appendicectomy) compared with antibiotics.

INTRODUCTION
The prevalence of appendiceal endometriosis ranges from 0.4% to 22%. The carcinoid tumor is the most common neoplasm of the appendix, with incidence ranging from 0.3% to 0.9%. Appendix lesions develop in up to 22% of women with deep infiltrative endometriosis. Even though these are most likely endometriosis, carcinoid tumors should always be considered. The aim of this review was to assess the prevalence of appendiceal carcinoid tumors and appendiceal endometriosis in patients undergoing gynecologic surgery, its association with endometriosis, and related symptoms.
EVIDENCE ACQUISITION
We included retrospective and prospective studies that assessed women who underwent appendicectomy in the past 20 years for appendiceal endometriosis and/or appendix carcinoid tumor confirmed by histological analysis. Results were reported as relative and absolute frequencies. Due to the heterogeneity of included studies, a statistical analysis (meta-analysis) was not performed.
EVIDENCE SYNTHESIS
The prevalence of appendiceal endometriosis was 15.2% in patients who underwent surgery for pelvic endometriosis and 11.4% in those who underwent benign gynecological surgery. Conversely, carcinoid tumors of the appendix were present in 2.4% of endometriosis patients and 1.3% of other benign gynecological surgeries.
CONCLUSIONS
The rates of carcinoid tumors in patients with endometriosis are the same as in the general population. Given the risk of a malignant appendiceal tumor, in all gynecological surgeries, especially those for endometriosis, the appendix should be inspected and removed if it has an abnormal appearance.
