The dose-response relationship between physical activity and school scoliosis screening positive in children and adolescents: a preliminary cross-sectional study.

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: While physical inactivity is an established risk factor for adolescent idiopathic scoliosis (AIS), dose-response relationships for physical activity (PA) parameters remain unquantified. This study examined associations between PA dose (amount, duration, frequency, type) and scoliosis screening positive (SSP), exploring optimal thresholds. Methods: In this cross-sectional analysis, 1,051 students (mean age 10.69 ± 2.45 years) from 8 Shanghai schools underwent scoliometer screening (ATR ≥5° defined as SSP). PA was assessed via validated The Physical Activity Questionnaire for Older Children(PAQ-C) questionnaire[scores≤2: light PA(LPA), scores2-3: moderate PA(MPA), scores > 3: vigorous PA(VPA)]. Logistic regression modeled scoliosis risk across PA strata. Restricted cubic splines (RCS) characterized dose-response curves. Subgroup analyses explored age-specific effects. Results: In two multivariable-adjusted models, both LPA and VPA demonstrated significantly elevated risks for SSP compared to MPA (adjusted OR = 3.30, 95% CI 1.92-5.68 and OR = 3.65, 95% CI 2.14-6.24, respectively), revealing a U-shaped dose-response relationship with risk nadir at PAQ-C scores≈2.7(p < 0.05). Exercise frequency <3 sessions/week (OR = 4.68, 95% CI 2.75-7.98), session duration <∼54 min or >90 min (OR = 3.43 and 2.75), and cumulative participation >2 years (OR = 3.37, 95% CI 1.89-6.01) were positively associated with SSP ( Conclusions: The amount of physical activity in children and adolescents shows a U-shaped association with SSP, with moderate PA (approximately 54 min/day, 3-4 days/week) being associated with the lowest SSP odds, while low and vigorous PA are associated with higher odds. Participation in water sports and team sports is inversely associated with SSP.These findings highlight potential associations that warrant further longitudinal investigation.
