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.

2 · The registry

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

This retrospective cohort study examined associations between maternal body mass index (BMI), race, and obstetric anal sphincter injury (OASI) (3rd/4th degree perineal lacerations). Obstetric anal sphincter injury may lead to significant maternal morbidity, and a more thorough understanding of risk factors for this complication may guide providers in patient counseling and procedures such as episiotomy or operative vaginal delivery. Vaginal deliveries performed at Kapi'olani Medical Center for Women and Children from 2008-2015 were included. Maternal body mass index at delivery was used and OASIs identified through International Classification of Diseases codes. Demographic/clinical variables were summarized through descriptive statistics. Adjusted odds ratios were calculated using multiple logistic regression. Of the 25,594 deliveries included, 1,198 (4.7%) involved an OASI. OASI prevalence differed by BMI (P < .0001). The prevalence was highest in women with BMI < 30 kg/m
