Early versus late amniotomy during twin labor.

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
objectiveThis study evaluates whether timing of amniotomy affects labor characteristics and maternal and neonatal outcomes in twin deliveries.
methodsThis retrospective study was conducted at a single academic medical center and included dichorionic diamniotic (DCDA) twin pregnancies with a normal anomaly scan and a vertex-presenting leading twin, delivered over a 7-year period. The cohort was divided into two groups: early amniotomy (performed at cervical dilation ≤3 cm) and late amniotomy (performed at >3 cm cervical dilation). Exclusion criteria included monochorionic twin pregnancies and planned elective cesarean deliveries. Maternal demographics, delivery characteristics, and neonatal outcomes were compared between groups.
resultsOf 51 592 deliveries, 1196 were twins; 565 DCDA pregnancies met the inclusion criteria (early n = 279; late n = 286). Groups were similar in age, body mass index (kg/m
conclusionIn DCDA twin labor, early amniotomy (≤3 cm) is associated with increased intrapartum cesarean, despite similar durations of labor and neonatal outcomes. Amniotomy timing should be individualized, with caution against routine early rupture.
