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

objectiveLabor induction is offered to reduce the risk of stillbirth at late term (41

methodsThis was a retrospective cohort study including 70 293 singleton term births in Iceland during 1997-2018. Women with serious pre-gestational comorbidity, hypertension, stillbirth or previous cesarean birth were excluded. The risk of adverse maternal and neonatal outcomes for induction at each week from gestational age 37-41 weeks was compared with expectant management, defined as deliveries at a later gestational age. Risk ratios (RRs) and 95% confidence intervals (95% CI) were calculated using log-binomial regression adjusting for sociodemographics, parity, and pregnancy complications.

resultsThe risk of cesarean was lower with induction at ≥40

conclusionLabor induction from 40
