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

introduction and hypothesisThe aim of the mediolateral episiotomy incision is to increase the diameter of the soft tissue of the vaginal outlet to facilitate birth and to prevent vaginal tears. Episiotomy angles that are too narrow and close to the midline increase the risk of obstetric anal sphincter injuries. In order to determine the optimal angle of the episiotomy, we assessed the changes in the angles of episiotomy lines marked during the first stage of labor and measured at the time of crowning of the head.

methodsIncision lines for mediolateral episiotomy were marked on the perineal skin at angles of 30°, 45°, and 60° from the midline during the first stage of labor in women with a singleton pregnancy. The angles of the marked lines were measured at crowning of the head. Mediolateral episiotomy was performed only for obstetric indications.

resultsThe study included 102 women with a singleton pregnancy. Of these women, 50 were primiparous and 52 were multiparous. All angles marked during the first stage of labor increased significantly (by more than 30°) at crowning of the head. Similar changes were observed in primiparous and multiparous women.

conclusionsThe angle of the mediolateral episiotomy line was significantly greater at crowning of the head than when marked during the first stage of labor. To achieve the desired episiotomy angle, it is important to take into consideration the changes in mediolateral episiotomy angles that occur during labor.
