Synthesis in International urogynecology journal, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT02582580 (Effects of Perineal Massage, Vaginal Dilator and Pelvic Floor Muscles Training on the Perineal Integrity Primiparous), which is not on this map. Cited by 14 papers, 4 of them syntheses that pooled it.

1 · What the graph read from it

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.

Abstract

introduction and hypothesisIn this systematic review we aimed to assess if the Epi-No birth trainer used during antepartum could prevent perineal trauma in nulliparous women.

methodsWe searched CENTRAL, MEDLINE, EMBASE, Scielo, and Conference abstracts, looking for randomized controlled studies (RCT). High heterogeneity (i(2) > 50 %) was corrected with random models. All studies were analyzed according to their quality and risk of bias. Nulliparous women or women whose previous pregnancy ended before 21 weeks' gestation were included and the main outcome measures were: episiotomy rates, perineal tears, severe (3rd/4th) perineal tears, and intact perineum.

resultsFive studies were included (1,369 participants) for systematic review and two of them (932 participants) were eligible for meta-analysis. Epi-No did not reduce episiotomy rates (RR 0.92 [95%CI 0.75-1.13], n = 710, p =0.44; two studies; fixed model) and second stage of labor (MD -12.50 [95%CI -29.62, -4.62], n = 162, p = 0.54; one study; fixed model), and did not increase intact perineum (RR 1.15 [95 % CI 0.81-1.64], n = 705, p = 0.43; two studies; random model). No influence of Epi-No on reducing all perineal tears (RR 0.99 [95%CI 0.84-1.17], n = 705, p = 0.93, two studies; fixed model) or severe (3rd/4th) perineal tears (RR 1.31 [95%CI 0.72-2.37], n = 705, p = 0.38, two studies; fixed model). Mean birthweight of the Epi-No group was higher than that of the control group in both studies, with no statistical significance.

conclusionEpi-No birth trainer is a device that did not reduce episiotomy rates and had no influence on reducing perineal tears.
