Stillbirths in a large Shanghai maternity centre (2014-2024): trends, sex distribution, and gestational age-specific risk.
Article in BMC pregnancy and childbirth, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
backgroundStillbirth is a catastrophic adverse pregnancy outcome that harms families and is a major global public health concern; however, the available data regarding its prevalence, sex disparities, and gestational age distribution (key for targeted interventions) are insufficient. This study addressed this gap in a large Shanghai pregnant cohort.
methodsThis retrospective study included 140,594 pregnant women (after incomplete/nonsingleton cases were excluded) who delivered at a tertiary hospital (Oct 2014–Sep 2024). Stillbirth was defined per the WHO guidelines (≥ 28 weeks). Stillbirth rates were calculated overall and stratified by foetal sex/gestational age (28–31, 32–36, and ≥ 37weeks). Mann‒Kendall test was used to assess trends (2015–2023), chi-square tests were used to compare subgroups, and analyses were performed in R 4.5.1 (P < 0.05 indicates statistical significance).
resultsAmong 140,594 deliveries, 249 stillbirths occurred (rate: 0.18%; 95% CI: 0.16–0.20%). The increasing trend from 2015–2023 was nonsignificant (Z = 0.738, P = 0.461; tau = 0.229), with no sex disparities (males: 51.81%; 129/249; females: 48.19%; 120/249; χ²=0.325; P = 0.5684). Regardless of sex, stillbirths were more common at 28–31 weeks and fewer at ≥ 37 weeks (male: χ²=28.79; female: χ²=21.05; P < 0.001).
conclusionsStillbirth rate in our maternity centre has remained consistently low over the past decade, with no significant temporal increase or sex-based disparities observed. The risk of stillbirth decreased with advancing gestational age, with the highest risk noted at 28–31 weeks; these findings underscore the need for targeted monitoring and interventions during the early phase of late pregnancy. Future multicentre studies are warranted to validate these findings and provide evidence to inform stillbirth prevention strategies.
