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 estimate a stillbirth rate at 24 or more gestational weeks in 2015-2016 and to explore potentially preventable causes in China.

designA multi-centre cross-sectional study.

settingNinety-six hospitals distributed in 24 (of 34) provinces in China. POPULATION: A total of 75 132 births at 24 completed weeks of gestation or more.

methodsCOX Proportional Hazard Models were performed to examine risk factors for antepartum and intrapartum stillbirths. Population attributable risk percentage was calculated for major risk factors. Correspondence analysis was used to explore region-specific risk factors for stillbirths.

main outcome measuresStillbirth rate and risk factors for stillbirth.

resultsA total of 75 132 births including 949 stillbirths were used for the final analysis, giving a weighted stillbirth rate of 13.2 per 1000 births (95% CI 7.9-18.5). Small for gestational age (SGA) and pre-eclampsia/eclampsia increased antepartum stillbirths by 26.2% and 11.7%, respectively. Fetal anomalies increased antepartum and intrapartum stillbirths by 17.9% and 7.4%, respectively. Overall, 31.4% of all stillbirths were potentially preventable. Advanced maternal age, pre-pregnant obesity, chronic hypertension and diabetes mellitus were important risk factors in East China; low education and SGA were major risk factors in Northwest, Southwest, Northeast and South China; and pre-eclampsia/eclampsia and intrapartum complications were significant risk factors in Central China.

conclusionsThe prevalence of stillbirth was 13.2 per 1000 births in China in 2015-2016. Nearly one-third of all stillbirths may be preventable. Strategies based on regional characteristics should be considered to reduce further the burden of stillbirths in China. TWEETABLE ABSTRACT: The stillbirth rate was 13.2 per 1000 births in China in 2015-2016 and nearly one-third of all stillbirths may be preventable.
