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

backgroundThe best timing of delivery for term pregnancies has not been determined. This retrospective cohort study compared pregnancy outcomes between induction of labor (IOL) at 40 weeks and 41 weeks in low-risk women with singleton pregnancies and investigated maternal motivations regarding elective IOL.

methodsA total of 603 pregnant women were included in this study, with 342 (56.7%) undergoing IOL at 40-40

resultsThe rate of CS was 25.1% in the IOL at 40-40

conclusionsIOL at 40 weeks did not result in increased adverse outcomes compared to IOL at 41 weeks. Parturients with higher education and income were more likely to choose elective IOL. Parity ≥ 1 and a Bishop score ≥ 6 were protective factors against CS following IOL. These may provide a new option for clinical decision-making.
