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 hypothesisThe aim of this study was to assess the occurrence of severe perineal lacerations in vaginal delivery and its relationship with predisposing clinical and obstetric factors.

methodsA retrospective cohort analysis using an electronic clinical database at a University Referral Center for high-risk pregnancies was performed. A total of 941 vaginal deliveries were analyzed, over 10 consecutive months in 2013 and 2014. The relationship between obstetric and clinical characteristics and lacerations, especially severe forms, was analyzed. The frequency and severity of birth canal lacerations were compiled and classified as mild (unintentional laceration grades I and II, and mediolateral episiotomy) and severe (grades III and IV). The crude and adjusted odds ratios and 95% confidence intervals were estimated in univariate and multivariate logistic regression models.

resultsThe overall incidence of perineal lacerations in vaginal delivery was 78.2% (n = 731). Lacerations were considered mild in 708 women (75.7%) and severe in 23 women (2.5%). Maternal age, parity, use of forceps, mediolateral episiotomy, and birth weight influenced the occurrence of some degree of tear. The chance of severe lacerations increased 1.77-fold per week with the gestational age (1.03-3.03, P = 0.025), while primiparity increased the chance of laceration 5.32-fold. Episiotomy did not show a protective effect against severe laceration occurrence (P = 0.999).

conclusionsSevere perineal lacerations were associated with operative delivery, primiparity, gestational age, and epidural anesthesia. Episiotomy was not protective.
