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

Extreme temperature events (ETEs) are associated with an increased risk of stillbirth. We conducted a nationwide cohort study based on China Birth Cohort Study (CBCS) across 17 provinces in 2018-2022. A set of cutoff temperature thresholds (2.5th, 5th, 7.5th, 10th, 90th, 92.5th, 95th and 97.5th percentiles of daily apparent temperature of each province during the study period) and durations (at least 2, 3, and 4 consecutive days) were utilized to define 24 distinct ETEs. We show that heatwave exposure was associated with a 36-83% increase in stillbirth. Overall, the adverse impact of cold spells on stillbirths is not significant. The effects varied across regions, and lower population density and greater medical resource were protective factors for the effects. Furthermore, when exposed to ETEs, small vulnerable newborns (SVN) are more likely to experience stillbirth. Our study highlights the need for adaptive and mitigative strategies against ETEs' adverse effects on stillbirth.
