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

objectiveTo explore term mortality rates in relation to rates of early-term birth (gestational ages 37 + 0 to 38 + 6 weeks), regarded as a proxy indicator of practices of elective birth by induction or caesarean.

designEcological study using national birth data.

setting28 European countries. POPULATION: Births ≥ 37 weeks between 2015 and 2020.

methodsAggregated data on live and stillbirths by completed week of gestation was compiled from routine sources in the Euro-Peristat network. Countries were divided into three groups based on their percentages of early-term births using terciles (high, medium and low) and mortality rates were compared between groups with random-effects meta-analysis of proportions.

main outcome measuresStillbirths (antepartum or intrapartum fetal death) and perinatal death (stillbirth or early neonatal death) per 1000 total births ≥ 37 weeks.

resultsEarly-term birth rates ranged from 17.8% (Iceland) to 49.1% (Cyprus), with terciles being < 21%, 21%-27%, and > 27%. Post-term birth rates were low in countries with higher early-term birth rates. The pooled stillbirth rate ≥ 37 weeks was 1.28 per 1000 total births (95% CI: 1.13-1.46) in the lowest tercile and 1.05 (95% CI: 0.95-1.16) in the highest (p = 0.05), but prediction intervals were wide reflecting heterogeneity within groups. No evidence of difference was seen between perinatal mortality rates by tercile (p = 0.71).

conclusionOn average, the stillbirth rate was lower in countries where early-term birth rates were highest, but no difference was found in perinatal mortality rates. Heterogeneity was high within groups.
