Impact of subsequent birth and delivery mode for women with previous OASIS: systematic review and meta-analysis.
Synthesis in International urogynecology journal, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 papers, 1 of them a synthesis that pooled 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.
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
introduction and hypothesisObstetric anal sphincter injuries (OASIS) are serious complications of vaginal birth. In a pregnancy following OASIS women may be keen to avoid an elective caesarean section, yet cautious about pursuing another vaginal birth that may result in further damage to the pelvic floor and possible long-term anal incontinence. This review aimed to evaluate the impact of subsequent birth and its mode on anal incontinence (AI) and/or quality of life (QoL), for women with previous OASIS.
methodsSearches of MEDLINE, EMBASE, CINAHL, and AMED from inception to February 2016 were undertaken with selection criteria of any study evaluating the effect of a subsequent birth on AI and/or QoL in women with previous OASIS. Where possible, data were extracted to populate 2 × 2 tables and allow meta-analysis relating to the impact of subsequent birth on AI and/or QoL.
resultsTwenty-seven non-randomised studies were included. Meta-analysis of 14 studies (977 women) did not demonstrate any significant associations between AI in women with previous OASIS and subsequent birth or its mode. Impact on QoL was reported in 12 studies (912 women); however, difference in outcome reporting precluded data meta-analysis.
conclusionsComparisons of outcomes and effective synthesis were limited by sample size, quality and heterogeneity of the studies included. Consequently, the optimal mode of delivery for women with previous OASIS is still not known and better data are needed.
