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

The objective of this study was to identify factors associated with anal sphincter laceration in primiparous women. A subpopulation of 40,923 primiparous women at term with complete data sets was abstracted from a state-wide perinatal database in Germany. Outcome variable was anal sphincter laceration. Independent variables were 17 known obstetrical risk factors/conditions/interventions impacting childbirth recorded on the perinatal data collection sheet. Cross table analysis followed by logistic regression analysis was used for data analysis. Logistic regression showed episiotomy (OR, 3.23; CI, 2.73-3.80) and forceps delivery (OR, 2.68, CI, 2.17-3.33) to be most strongly associated with anal sphincter laceration. Women with a BMI >or= 30 kg/m2, and smokers had a significantly lower risk of anal sphincter laceration. Local, pudendal, and epidural analgesia all reduced the risk of anal sphincter laceration. Iatrogenic factors most strongly associated with anal sphincter laceration in primiparous women include routine episiotomy and forceps delivery.
