The use of misoprostol before hysteroscopy in Nulliparous women: a systematic review and meta-analysis of randomized controlled trials.
Synthesis in BMC pregnancy and childbirth, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesTo assess the value of misoprostol intake before hysteroscopy in nulliparous women. SEARCH STRATEGY: Databases screening was done from inception to July 2023 using "Misoprostol" AND "Hysteroscopy" AND "Nullipara" and their MeSH terms as keywords. SELECTION CRITERIA: Thirteen studies were included in our analysis. Seven studies compared misoprostol to placebo, 3 studies compared it to dinoglandin, 1 study compared it to diclofenac and 4 studies compared different misoprostol doses and routes. These studies were conducted on 1528 participants,958 of them received misoprostol, 221 received dinoglandin, 51 received diclofenac and 308 received placebo. DATA COLLECTION AND ANALYSIS: Extracted data included study place, participants number, inclusion and exclusion criteria, intervention details as dose, route, timing and comparotor, and hysteroscopy details. MAIN
resultsEase of cervical dilatation was reported in 3 studies (309 participants) and revealed an effect estimate mean difference (MD) of -0.57 [-1.72, 0.58] and a P value of 0.33. The time needed for cervical dilatation was reported in 6 studies (512 participants) and revealed a MD of -22.96 [-43.29, -2.62] and a P value of 0.03. The preoperative cervical width was reported in 4 studies (263 participants) and revealed MD of 1.69 [-0.09, 3.46] and a P value of 0.06. The number of women with failure of cervical dilatation or who needed further dilatation was reported in 4 studies (372 participants) and revealed a MD of 0.40 with [0.13, 1.17] 95% CI and a P value of 0.09. The preoperative pain was reported in 3 studies (351 participants) and revealed a MD of -0.56 [-2.30, 1.18] and a P value of 0.53. Total number of cases who experienced side effects and procedure complications were reported in 2 and 3 studies (249 and 252 participants) respectively and revealed an effect estimate Odd Ratio of 1.99 and 0.42 with [0.27, 14.67] and [0.14,1.32] 95% CI and a P value of 0.50 and 0.14 respectively. In the 3 studies comparing misoprostol to dinoglandin, The ease of cervical dilatation, time needed for cervical dilatation and preoperative cervical width were evaluated in 1,3 and 2 studies with 60, 436 and 376 participants respectively. The estimated MD were not estimated, 0.17 and 0.01; 95% CI were not estimated, [-4.70, 5.05], and [-0.78, 0.79]; P values of 0.94, 0.98 and 0.99 and I
conclusionMisoprostol improved the time needed for cervical dilatation without affecting the rate of complications or drug side effects when compared to placebo but has similar outcomes to dinoglandin with higher side effects. REGISTRATION NUMBER: CRD42023438432.
