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
Introduction: Faced with a declining birth rate, China urgently needs to identify effective strategies to improve residents' attitudes toward having additional children. This study investigates whether physical exercise, grounded in leisure theory and demographic principles, serves as a significant factor in promoting positive fertility attitudes. Methods: This research employs a conceptual framework that identifies the prerequisites and inherent benefits of physical exercise. We then empirically test its influence using data from the 2023 Chinese General Social Survey (CGSS). The desire for another child is the key outcome variable, regressed on measures of sports participation. Robustness checks are conducted to address potential endogeneity, and a mediation analysis is performed to uncover the underlying pathways. Results: The results demonstrate that participation in sports activities substantially improves individuals' fertility attitudes. This positive effect remains robust after controlling for endogeneity. The mediation analysis reveals that the relationship is driven by two significant pathways: first, through the enhancement of physical and mental health, and second, through the strengthening of family cohesion and overall life satisfaction. Discussion: The findings confirm that physical exercise is a significant and positive predictor of fertility attitudes in China. The mechanisms operate through both bio-psychological and socio-familial channels. We conclude that public policies aimed at promoting accessible and appealing physical exercise can effectively complement existing fertility support measures, thereby providing a viable strategy to help optimize China's national population policies.
