The Spontaneous Abortion of Females is Influenced by Their Male Partner's Heat Wave Exposure During Adolescence: A Nationwide Observational Study in China.
Observational study in Current medical science, 2025. 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
objectiveHeat wave exposure significantly impacts human health. Nevertheless, studies on the long-term effects of heat wave exposure during adolescence on adverse pregnancy outcomes (APOs) are rare. This study aimed to investigate the relationship between the long-term effects of heat wave exposure during adolescence and APOs.
methodsWe analyzed data from 3,376 female and 3,013 male participants across 31 provinces in China. All adolescents (10-19 years old), early adolescents (10-14), and late adolescents (15-19) were chosen as exposure windows. Heat waves were defined as periods lasting 2‒4 consecutive days with the daily temperature exceeding the 75th, 90th, and 92.5th percentiles. We employed multivariate logistic regression models to assess the associations between exposure to heat waves during adolescence and APOs.
resultsThe results revealed significant associations between male exposure to heat wave events during late adolescence and spontaneous abortion (P < 0.05), which was more pronounced in South China. In contrast, no statistically significant associations were detected between males' exposure to heat wave events during adolescence and their partners' preterm birth (P > 0.05 for all comparisons). The exposure of females to heat waves during adolescence was not significantly associated with subsequent spontaneous abortion or preterm birth (P > 0.05 for all comparisons).
conclusionsThis study demonstrates that spontaneous abortion in females is associated with heat wave exposure in their male partner during adolescence.
