The association between physical activity and adolescent idiopathic scoliosis: improper sitting posture as a mediator.

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
Background: The association between physical activity (PA) and adolescent idiopathic scoliosis (AIS) remains unclear. This study investigates whether improper sitting posture mediates the relationship between PA and AIS in cross-sectional analyses. Methods: This study utilized data on adolescents collected across 9 provinces in China in 2021, involving 3,536 participants for cross-sectional analysis. A multivariate logistic regression model was used to evaluate the associations among PA, improper sitting posture, and AIS. Mediation analyses assessed the mediating role of improper sitting posture in the association between PA and AIS. Subgroup analyses were performed to assess heterogeneity across groups. Results: In the cross-sectional analysis, PA (OR = 0.985, 95%CI: 0.981-0.990, Conclusion: PA was negatively associated with improper sitting posture and AIS, and improper sitting posture was positively associated with AIS. Improper sitting posture partially mediated the association between PA and AIS. These results suggest that PA and the avoidance of improper sitting posture may help prevent AIS.
