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

objectiveWe sought to study neonatal outcomes in early preterm births by delivery route. STUDY

designDelivery precursors were analyzed in 4352 singleton deliveries, 24 0/7 to 31 6/7 weeks' gestation. In a subset (n = 2906) eligible for a trial of labor, neonatal mortality in attempted vaginal delivery (VD) was compared to planned cesarean delivery stratified by presentation.

resultsDelivery precursors were classified as maternal or fetal conditions (45.7%), preterm premature rupture of membranes (37.7%), and preterm labor (16.6%). For vertex presentation, 79% attempted VD and 84% were successful. There was no difference in neonatal mortality. For breech presentation, at 24 0/7 to 27 6/7 weeks' gestation, 31.7% attempted VD and 27.6% were successful; neonatal mortality was increased (25.2% vs 13.2%, P = .003). At 28 0/7 to 31 6/7 weeks' gestation, 30.5% attempted VD and 17.2% were successful; neonatal mortality was increased (6.0% vs 1.5%, P = .016).

conclusionAttempted VD for vertex presentation has a high success rate with no difference in neonatal mortality unlike breech presentation.
