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

introductionInduction of labor (IOL) rates have been increasing in high-income countries. Although IOL aims to reduce maternal and neonatal morbidity, the benefits for many common indications remain uncertain. Because IOL may also have disadvantages and place a burden on the health-care system, it is important to clarify the factors underlying the rising national IOL rates. MATERIAL AND

methodsThis descriptive study included all singleton births in cephalic presentation delivered at 37

resultsThe study sample included 880 478 births. The IOL rate doubled from 18% to 36%. In the IOL group, the most prevalent and increasingly common factors were maternal age ≥35 years, BMI ≥30 kg/m

conclusionsThe main contributors to the increasing IOL rate were the increased prevalence of advanced maternal age, obesity, and gestational diabetes. The increases in the prevalence of other IOL indications were less extensive.
