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

aimThis study evaluated the association between body mass index (BMI) at the onset of labor induction and delivery outcomes, including instrumental delivery, emergency cesarean section, labor duration, and cumulative oxytocin dose among singleton term pregnancies.

methodsWe conducted a retrospective cohort study of singleton term pregnancies undergoing labor induction at a tertiary perinatal center. We analyzed BMI at induction onset as a continuous variable and applied multivariable regression models to evaluate instrumental delivery, emergency cesarean section, labor duration, and cumulative oxytocin dose. We also performed sensitivity analyses using pre-pregnancy BMI, models additionally adjusting for gestational weight gain and pregnancy complications, and restricted-indication analyses.

resultsDelivery BMI was not significantly associated with instrumental delivery (adjusted OR 0.96 per 1 kg/m

conclusionsHigher maternal BMI at induction onset was associated with greater oxytocin requirements, while no clear associations were observed with mode of delivery or labor duration.
