Meta-Analysis Review
IMPORTANCE
Between 40% and 50% of women in Western countries use complementary therapies to manage menopausal symptoms.
OBJECTIVE
To determine the association of plant-based therapies with menopausal symptoms, including hot flashes, night sweats, and vaginal dryness.
DATA SOURCES
The electronic databases Ovid MEDLINE, EMBASE, and Cochrane Central were systematically searched to identify eligible studies published before March 27, 2016. Reference lists of the included studies were searched for further identification of relevant studies.
STUDY SELECTION
Randomized clinical trials that assessed plant-based therapies and the presence of hot flashes, night sweats, and vaginal dryness.
DATA EXTRACTION
Data were extracted by 2 independent reviewers using a predesigned data collection form.
MAIN OUTCOMES AND MEASURES
Hot flashes, night sweats, and vaginal dryness.
RESULTS
In total, 62 studies were identified, including 6653 individual women. Use of phytoestrogens was associated with a decrease in the number of daily hot flashes (pooled mean difference of changes, -1.31 [95% CI, -2.02 to -0.61]) and vaginal dryness score (pooled mean difference of changes, -0.31 [95% CI, -0.52 to -0.10]) between the treatment groups but not in the number of night sweats (pooled mean difference of changes, -2.14 [95% CI, -5.57 to 1.29]). Individual phytoestrogen interventions such as dietary and supplemental soy isoflavones were associated with improvement in daily hot flashes (pooled mean difference of changes, -0.79 [-1.35 to -0.23]) and vaginal dryness score (pooled mean difference of changes, -0.26 [-0.48 to -0.04]). Several herbal remedies, but not Chinese medicinal herbs, were associated with an overall decrease in the frequency of vasomotor symptoms. There was substantial heterogeneity in quality across the available studies, and 46 (74%) of the included randomized clinical trials demonstrated a high risk of bias within 3 or more areas of study quality.
CONCLUSIONS AND RELEVANCE
This meta-analysis of clinical trials suggests that composite and specific phytoestrogen supplementations were associated with modest reductions in the frequency of hot flashes and vaginal dryness but no significant reduction in night sweats. However, because of general suboptimal quality and the heterogeneous nature of the current evidence, further rigorous studies are needed to determine the association of plant-based and natural therapies with menopausal health.

Review
OBJECTIVE
To comprehensively review and critically assess the literature on vaginal estrogen and its alternatives for women with genitourinary syndrome of menopause and to provide clinical practice guidelines.
DATA SOURCES
MEDLINE and Cochrane databases were searched from inception to April 2013. We included randomized controlled trials and prospective comparative studies. Interventions and comparators included all commercially available vaginal estrogen products. Placebo, no treatment, systemic estrogen (all routes), and nonhormonal moisturizers and lubricants were included as comparators.
METHODS OF STUDY SELECTION
We double-screened 1,805 abstracts, identifying 44 eligible studies. Discrepancies were adjudicated by a third reviewer. Studies were individually and collectively assessed for methodologic quality and strength of evidence.
TABULATION, INTEGRATION, AND RESULTS
Studies were extracted for participant, intervention, comparator, and outcomes data, including patient-reported atrophy symptoms (eg, vaginal dryness, dyspareunia, dysuria, urgency, frequency, recurrent urinary tract infection (UTI), and urinary incontinence), objective signs of atrophy, urodynamic measures, endometrial effects, serum estradiol changes, and adverse events. Compared with placebo, vaginal estrogens improved dryness, dyspareunia, urinary urgency, frequency, and stress urinary incontinence (SUI) and urgency urinary incontinence (UUI). Urinary tract infection rates decreased. The various estrogen preparations had similar efficacy and safety; serum estradiol levels remained within postmenopausal norms for all except high-dose conjugated equine estrogen cream. Endometrial hyperplasia and adenocarcinoma were extremely rare among those receiving vaginal estrogen. Comparing vaginal estrogen with nonhormonal moisturizers, patients with two or more symptoms of vulvovaginal atrophy were substantially more improved using vaginal estrogens, but those with one or minor complaints had similar symptom resolution with either estrogen or nonhormonal moisturizer.
CONCLUSION
All commercially available vaginal estrogens effectively relieve common vulvovaginal atrophy-related complaints and have additional utility in patients with urinary urgency, frequency or nocturia, SUI and UUI, and recurrent UTIs. Nonhormonal moisturizers are a beneficial alternative for those with few or minor atrophy-related symptoms and in patients at risk for estrogen-related neoplasia.

Review
The results of large clinical trials have led physicians and patients to question the safety of hormone therapy for menopause. In the past, physicians prescribed hormone therapy to improve overall health and prevent cardiac disease, as well as for symptoms of menopause. Combined estrogen/progestogen therapy, but not estrogen alone, increases the risk of breast cancer when used for more than three to five years. Therefore, in women with a uterus, it is recommended that physicians prescribe combination therapy only to treat menopausal symptoms such as vasomotor symptoms (hot flashes) and vaginal atrophy, using the smallest effective dosage for the shortest possible duration. Although estrogen is the most effective treatment for hot flashes, nonhormonal alternatives such as low-dose paroxetine, venlafaxine, and gabapentin are effective alternatives. Women with a uterus who are using estrogen should also take a progestogen to reduce the risk of endometrial cancer. Women who cannot tolerate adverse effects of progestogens may benefit from a combined formulation of estrogen and the selective estrogen receptor modulator bazedoxifene. There is no highquality, consistent evidence that yoga, paced respiration, acupuncture, exercise, stress reduction, relaxation therapy, and alternative therapies such as black cohosh, botanical products, omega-3 fatty acid supplements, and dietary Chinese herbs benefit patients more than placebo. One systematic review suggests modest improvement in hot flashes and vaginal dryness with soy products, and small studies suggest that clinical hypnosis significantly reduces hot flashes. Patients with genitourinary syndrome of menopause may benefit from vaginal estrogen, nonhormonal vaginal moisturizers, or ospemifene (the only nonhormonal treatment approved by the U.S. Food and Drug Administration for dyspareunia due to menopausal atrophy). The decision to use hormone therapy depends on clinical presentation, a thorough evaluation of the risks and benefits, and an informed discussion with the patient.

BACKGROUND
The decline in postmenopausal serum estrogen concentration results in several changes in the vulvovaginal and vesicourethral areas, resulting in the genitourinary syndrome of menopause, including symptoms such as vaginal atrophy.
AIM
To evaluate the effects of hyaluronic acid in vaginal atrophy.
METHODS
A search strategy was developed using the following terms: "Hyaluronic Acid vaginal gel," "vaginal estrogens," "Vaginitis, Atrophic," and "Postmenopause." This strategy was used in major databases such as MEDLINE, EMBASE, Scopus, Cochrane library, Web of Science, Virtual Health Library (BVS), Congress Abstracts, and Gray Literature (Google Scholar and British Library) for studies published until June 2020.
OUTCOMES
A systematic review was carried out to assess the results of atrophic vaginitis/vaginal dryness, dyspareunia, vaginal pH, and cell maturation of the studies found by the search strategy.
RESULTS
A total of 833 studies were identified, 528 studies were directed for reading titles and abstracts, and 515 were excluded for not meeting the selection criteria. A total of 13 studies were selected for reading the full text. 5 primary studies involving 335 women met the criteria and were included. The studies were published between the years 2011 and 2017. It was not possible to perform meta-analysis owing to the substantial heterogeneity present in the studies. The results presented suggest that treatment with hyaluronic acid, when compared with the use of estrogens, does not present a significant difference in the results obtained for the outcomes: epithelial atrophy, vaginal pH, dyspareunia, and cell maturation.
CLINICAL TRANSLATION
Hyaluronic acid appears to be an alternative to non-hormonal treatments for the signs of vaginal atrophy and dyspareunia.
STRENGTHS & LIMITATIONS
The analysis of the studies in this systemic review suggests that hyaluronic acid has efficacy similar to vaginal estrogens for the treatment of the signs of vaginal atrophy and dyspareunia. However, the included studies measured the data in different ways, causing the performance of meta-analysis to be impaired.
CONCLUSION
The comparisons presented suggest that hyaluronic acid has a profile of efficacy, safety, and tolerability comparable with vaginal estrogens for the treatment of symptoms of vaginal atrophy. It is a possible alternative for women who cannot use hormonal treatment. dos Santos CCM, Uggioni MLR, Colonetti T, et al. Hyaluronic Acid in Postmenopause Vaginal Atrophy: A Systematic Review.

Meta-Analysis
BACKGROUND
Genitourinary syndrome of menopause (GSM) is a widespread condition with a great impact on quality of life and self-image.
AIM
We aimed to systematically review the current literature on CO2-Laser therapy efficacy for the treatment of GSM.
METHODS
MEDLINE and Embase databases were systematically queried in December 2020 Studies included women with a diagnosis of Vulvo-Vaginal Atrophy (VVA) or GSM without an history of gynaecological and/or breast cancer, pelvic organ prolapse staged higher than 2, pelvic radiotherapy or Sjogren's Syndrome. The quality of the evidence was assessed with the Cochrane risk of bias tool. This study is registered on PROSPERO, number CRD42021238121.
OUTCOMES
Effects of CO2-Laser therapy on GSM symptoms assessed through subjective or objective efficacy measurement methods.
RESULTS
A total of 803 articles were identified. Of these, 25 studies were included in this review for a total of 1,152 patients. All studies showed a significant reduction in VVA and/or GSM symptoms (dryness, dyspareunia, itching, burning, dysuria). The pooled mean differences for the symptoms were: dryness -5.15 (95% CI:-5.72,-4.58; P < .001; I:62%; n = 296), dyspareunia -5.27 (95% CI:-5.93,-4.62; P < .001; I:68%; n = 296), itching -2.75 (95% CI:-4.0,-1.51; P < .001; I:93%; n = 281), burning -2.66 (95% CI:-3.75, -1.57; P < .001; I:86%; n = 296) and dysuria -2.14 (95% CI:-3.41,-0.87; P < .001; I:95%; n = 281). FSFI, WHIS and VMV scores also improved significantly. The pooled mean differences for these scores were: FSFI 10.8 (95% CI:8.41,13.37; P < .001; I:84%; n = 273), WHIS 8.29 (95% CI:6.16,10.42; P < .001; I:95%; n = 262) and VMV 30.4 (95% CI:22.38,38.55; P < .001; I:24%; n = 68). CO2-Laser application showed a beneficial safety profile and no major adverse events were reported.
CLINICAL IMPLICATIONS
Vaginal laser treatment resulted in both a statistically and clinically significant improvement in GSM symptoms. FSFI improved significantly in all 8 included studies but it reached a clinically relevant level only in 2 of them.
STRENGTHS & LIMITATIONS
The strength of the current meta-analysis is the comprehensive literature search. We reported data from a high number of patients (1,152) and high number of laser applications (more than 3,800). The main limitations are related to the high heterogeneity of the included studies investigating laser effects. Moreover, most of them are single center and nonrandomized studies.
CONCLUSION
The data suggest that CO2-Laser is a safe energy-based therapeutic option for the management of VVA and/or GSM symptoms in postmenopausal women; however, the quality of the body of evidence is "very low" or "low".

Meta-Analysis Review
BACKGROUND
Pregnancy and childbirth increase the risk for pelvic floor dysfunction, including sexual dysfunction. So far, the mechanisms and the extent to which certain risk factors play a role remain unclear.
OBJECTIVES
In this systematic review of the literature we aimed to determine risk factors for sexual dysfunction in the first year after childbirth.
SEARCH STRATEGY
We searched MEDLINE, Embase and CENTRAL using the search strategy: sexual dysfunction AND obstetric events.
SELECTION CRITERIA
We included original, comparative studies, reported in English, that used validated questionnaires and the ICS/IUGA terminology for sexual dysfunction, dyspareunia and vaginal dryness.
DATA COLLECTION AND ANALYSIS
We assessed the quality and the risk of bias of the included studies with the Newcastle-Ottawa scale. We extracted the reported data and we performed random-effects meta-analysis to obtain the summary odds ratios (ORs) with 95% confidence intervals (95% CIs). Heterogeneity across studies was assessed using the I statistic.
MAIN RESULTS
Anal sphincter injury was associated with increased odds for both sexual dysfunction (OR 3.00, 95%CI 1.28-7.03) and dyspareunia (OR 1.92, 95% CI 1.47-2.52). Episiotomy was associated with dyspareunia (OR 1.64, 95% CI 1.25-2.14), but not with sexual dysfunction (OR 1.90, 95% CI 0.94-3.84). Compared with spontaneous birth, caesarean section reduced the odds for dyspareunia (OR 0.68, 95% CI 0.54-0.86) but not for sexual dysfunction (OR 1.14, 95% CI 0.89-1.46). Instrumental vaginal birth increased the odds for sexual dysfunction (OR 1.70, 95% CI 1.05-2.76), yet no difference was found for dyspareunia (OR 1.82, 95% CI 0.88-3.75). One study of low quality reported on vaginal dryness and found no association with obstetric events.
CONCLUSIONS
Perineal trauma, rather than mode of birth, increases the odds for sexual dysfunction in the first year after childbirth.

Meta-Analysis Review
The objective of this study is to determine whether dienogest therapy after endometriosis surgery reduces the risk of recurrence compared with placebo or alternative treatments (GnRH agonist, other progestins, and estro-progestins). The design used in this study is systematic review with meta-analysis. The data source includes PubMed and EMBASE searched up to March 2022. A systematic review and meta-analysis were performed in accordance with guidelines from the Cochrane Collaboration. Keywords such as "dienogest," "endometriosis surgery," "endometriosis treatment," and "endometriosis medical therapy" were used to identify relevant studies. The primary outcome was recurrence of endometriosis after surgery. The secondary outcome was pain recurrence. An additional analysis focused on comparing side effects between groups. Nine studies were eligible, including a total of 1668 patients. At primary analysis, dienogest significantly reduced the rate of cyst recurrence compared with placebo (p < 0.0001). In 191 patients, the rate of cyst recurrence comparing dienogest vs GnRHa was evaluated, but no statistically significant difference was reported. In the secondary analysis, a trend toward reduction of pain at 6 months was reported in patients treated with dienogest over placebo, with each study reporting a significantly higher reduction of pain after dienogest treatment. In terms of side effects, dienogest treatment compared with GnRHa significantly increased the rate of spotting (p = 0.0007) and weight gain (p = 0.03), but it was associated with a lower rate of hot flashes (p = 0.0006) and a trend to lower incidence of vaginal dryness. Dienogest is superior to placebo and similar to GnRHa in decreasing rate of recurrence after endometriosis surgery. A significantly higher reduction of pain after dienogest compared with placebo was reported in two separate studies, whereas a trend toward reduction of pain at 6 months was evident at meta-analysis. Dienogest treatment compared with GnRHa was associated with a lower rate of hot flashes and a trend to lower incidence of vaginal dryness.

Review
(1) Background: Genitourinary syndrome of menopause (GSM) is a medical condition that can affect breast cancer survivors (BCS). This is a complication that often can occur as a result of breast cancer treatment, causing symptoms such as vaginal dryness, itching, burning, dyspareunia, dysuria, pain, discomfort, and impairment of sexual function. BCS who experience these symptoms negatively impact multiple aspects of their quality of life to the point that some of them fail to complete adjuvant hormonal treatment; (2) Methods: In this systematic review of the literature, we have analyzed possible pharmacological and non-pharmacological treatments for GSM in BCS. We reviewed systemic hormone therapy, local hormone treatment with estrogens and androgens, the use of vaginal moisturizers and lubricants, ospemifene, and physical therapies such as radiofrequency, electroporation, and vaginal laser; (3) Results: The data available to date demonstrate that the aforementioned treatments are effective for the therapy of GSM and, in particular, vulvovaginal atrophy in BCS. Where possible, combination therapy often appears more useful than using a single line of treatment; (4) Conclusions: We analyzed the efficacy and safety data of each of these options for the treatment of GSM in BCS, emphasizing how often larger clinical trials with longer follow-ups are needed.

Meta-Analysis Review
BACKGROUND
Menopause can be a distressing and disruptive time for many women, with many experiencing hot flushes, night sweats, vaginal atrophy and dryness. Postmenopausal women are also at increased risk of osteoporosis. Interventions that decrease the severity and frequency of these menopausal symptoms are likely to improve a woman's well-being and quality of life. Hormone therapy has been shown to be effective in controlling the symptoms of menopause; however, many potentially serious adverse effects have been associated with this treatment. Evidence from experimental studies suggests that black cohosh may be a biologically plausible alternative treatment for menopause; even so, findings from studies investigating the clinical effectiveness of black cohosh have, to date, been inconsistent.
OBJECTIVES
To evaluate the clinical effectiveness and safety of black cohosh (Cimicifuga racemosa or Actaea racemosa) for treating menopausal symptoms in perimenopausal and postmenopausal women.
SEARCH METHODS
Relevant studies were identified through AARP Ageline, AMED, AMI, BioMed Central gateway, CAM on PubMed, CINAHL, CENTRAL, EMBASE, Health Source Nursing/Academic edition, International Pharmaceutical Abstracts, MEDLINE, Natural medicines comprehensive database, PsycINFO, TRIP database, clinical trial registers and the reference lists of included trials; up to March 2012. Content experts and manufacturers of black cohosh extracts were also contacted.
SELECTION CRITERIA
All randomised controlled trials comparing orally administered monopreparations of black cohosh to placebo or active medication in perimenopausal and postmenopausal women.
DATA COLLECTION AND ANALYSIS
Two review authors independently selected trials, extracted data and completed the 'Risk of bias' assessment. Study authors were contacted for missing information.
MAIN RESULTS
Sixteen randomised controlled trials, recruiting a total of 2027 perimenopausal or postmenopausal women, were identified. All studies used oral monopreparations of black cohosh at a median daily dose of 40 mg, for a mean duration of 23 weeks. Comparator interventions included placebo, hormone therapy, red clover and fluoxetine. Reported outcomes included vasomotor symptoms, vulvovaginal symptoms, menopausal symptom scores and adverse effects. There was no significant difference between black cohosh and placebo in the frequency of hot flushes (mean difference (MD) 0.07 flushes per day; 95% confidence interval (CI) -0.43 to 0.56 flushes per day; P=0.79; 393 women; three trials; moderate heterogeneity: I(2) = 47%) or in menopausal symptom scores (standardised mean difference (SMD) -0.10; 95% CI -0.32 to 0.11; P = 0.34; 357 women; four trials; low heterogeneity: I(2) = 21%). Compared to black cohosh, hormone therapy significantly reduced daily hot flush frequency (three trials; data not pooled) and menopausal symptom scores (SMD 0.32; 95% CI 0.13 to 0.51; P=0.0009; 468 women; five trials; substantial heterogeneity: I(2) = 69%). These findings should be interpreted with caution given the heterogeneity between studies. Comparisons of the effectiveness of black cohosh and other interventions were either inconclusive (because of considerable heterogeneity or an insufficient number of studies) or not statistically significant. Similarly, evidence on the safety of black cohosh was inconclusive, owing to poor reporting. There were insufficient data to pool results for health-related quality of life, sexuality, bone health, vulvovaginal atrophic symptoms and night sweats. No trials reported cost-effectiveness data. The quality of included trials was generally unclear, owing to inadequate reporting.
AUTHORS' CONCLUSIONS
There is currently insufficient evidence to support the use of black cohosh for menopausal symptoms. However, there is adequate justification for conducting further studies in this area. The uncertain quality of identified trials highlights the need for improved reporting of study methods, particularly with regards to allocation concealment and the handling of incomplete outcome data. The effect of black cohosh on other important outcomes, such as health-related quality of life, sexuality, bone health, night sweats and cost-effectiveness also warrants further investigation.

Meta-Analysis Review
BACKGROUND
Vaginal atrophy is a frequent complaint of postmenopausal women; symptoms include vaginal dryness, itching, discomfort and painful intercourse. Systemic treatment for these symptoms in the form of oral hormone replacement therapy is not always necessary. An alternative choice is oestrogenic preparations administered vaginally (in the form of creams, pessaries, tablets and the oestradiol-releasing ring). This is an update of a Chochrane systematic review; the original version was first published in October 2006.
OBJECTIVES
The objective of this review was to compare the efficacy and safety of intra-vaginal oestrogenic preparations in relieving the symptoms of vaginal atrophy in postmenopausal women.
SEARCH METHODS
We searched the following databases and trials registers to April 2016: Cochrane Gynaecology and Fertility Group Register of trials, The Cochrane Central Register of Controlled Trials (CENTRAL; 2016 issue 4), MEDLINE, Embase, PsycINFO, DARE, the Web of Knowledge, OpenGrey, LILACS, PubMed and reference lists of articles. We also contacted experts and researchers in the field.
SELECTION CRITERIA
The inclusion criteria were randomised comparisons of oestrogenic preparations administered intravaginally in postmenopausal women for at least 12 weeks for the treatment of symptoms resulting from vaginal atrophy or vaginitis.
DATA COLLECTION AND ANALYSIS
Two review authors independently assessed trial eligibility and risk of bias and extracted the data. The primary review outcomes were improvement in symptoms (participant-assessed), and the adverse event endometrial thickness. Secondary outcomes were improvement in symptoms (clinician-assessed), other adverse events (breast disorders e.g. breast pain, enlargement or engorgement, total adverse events, excluding breast disorders) and adherence to treatment. We combined data to calculate pooled risk ratios (RRs) (dichotomous outcomes) and mean differences (MDs) (continuous outcomes) and 95% confidence intervals (CIs). Statistical heterogeneity was assessed using the I(2) statistic. We assessed the overall quality of the evidence for the main comparisons using GRADE methods.
MAIN RESULTS
We included 30 RCTs (6235 women) comparing different intra-vaginal oestrogenic preparations with each other and with placebo. The evidence was low to moderate quality; limitations were poor reporting of study methods and serious imprecision (effect estimates with wide confidence intervals)1. Oestrogen ring versus other regimensOther regimens included oestrogen cream, oestrogen tablets and placebo. There was no evidence of a difference in improvement in symptoms (participant assessment) either between oestrogen ring and oestrogen cream (odds ratio (OR) 1.33, 95% CI 0.80 to 2.19, two RCTs, n = 341, I(2) = 0%, low-quality evidence) or between oestrogen ring and oestrogen tablets (OR 0.78, 95% CI 0.53 to 1.15, three RCTs, n = 567, I(2) = 0%, low-quality evidence). However, a higher proportion of women reported improvement in symptoms following treatment with oestrogen ring compared with placebo (OR 12.67, 95% CI 3.23 to 49.66, one RCT, n = 67). With respect to endometrial thickness, a higher proportion of women who received oestrogen cream showed evidence of increase in endometrial thickness compared to those who were treated with oestrogen ring (OR 0.36, 95% CI 0.14 to 0.94, two RCTs, n = 273; I(2) = 0%, low-quality evidence). This may have been due to the higher doses of cream used. 2. Oestrogen tablets versus other regimensOther regimens in this comparison included oestrogen cream, and placebo. There was no evidence of a difference in the proportions of women who reported improvement in symptoms between oestrogen tablets and oestrogen cream (OR 1.06, 95% CI 0.55 to 2.01, two RCTs, n = 208, I(2) = 0% low-quality evidence). A higher proportion of women who were treated with oestrogen tablets reported improvement in symptoms compared to those who received placebo using a fixed-effect model (OR 12.47, 95% CI 9.81 to 15.84, two RCTs, n = 1638, I(2) = 83%, low-quality evidence); however, using a random-effect model did not demonstrate any evidence of a difference in the proportions of women who reported improvement between the two treatment groups (OR 5.80, 95% CI 0.88 to 38.29). There was no evidence of a difference in the proportions of women with increase in endometrial thickness between oestrogen tablets and oestrogen cream (OR 0.31, 95% CI 0.06 to 1.60, two RCTs, n = 151, I(2) = 0%, low-quality evidence).3. Oestrogen cream versus other regimensOther regimens identified in this comparison included isoflavone gel and placebo. There was no evidence of a difference in the proportions of women with improvement in symptoms between oestrogen cream and isoflavone gel (OR 2.08, 95% CI 0.08 to 53.76, one RCT, n = 50, low-quality evidence). However, there was evidence of a difference in the proportions of women with improvement in symptoms between oestrogen cream and placebo with more women who received oestrogen cream reporting improvement in symptoms compared to those who were treated with placebo (OR 4.10, 95% CI 1.88 to 8.93, two RCTs, n = 198, I(2) = 50%, low-quality evidence). None of the included studies in this comparison reported data on endometrial thickness.
AUTHORS' CONCLUSIONS
There was no evidence of a difference in efficacy between the various intravaginal oestrogenic preparations when compared with each other. However, there was low-quality evidence that intra-vaginal oestrogenic preparations improve the symptoms of vaginal atrophy in postmenopausal women when compared to placebo. There was low-quality evidence that oestrogen cream may be associated with an increase in endometrial thickness compared to oestrogen ring; this may have been due to the higher doses of cream used. However there was no evidence of a difference in the overall body of evidence in adverse events between the various oestrogenic preparations compared with each other or with placebo.
