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

purposeThis study examined the associations between moderate-to-vigorous intensity physical activity (MVPA) and social support (SS), autonomous motivation (AM), community environment (CE), school environment (SE), and caregiver role modeling for physical activity (CRMPA) among school-aged children in south-central China.

methodsA multi-center survey was conducted with the recruitment of 706 children and their caregivers from six schools. MVPA was assessed using accelerometers over a one-week period, while the SS, AM, CE, SE, and CRMPA were assessed by validated questionnaires. Mediation analyses were used to evaluate the relationships between the aforementioned factors and MVPA.

resultsFor girls, SS (standardized estimate β = 0.25, 95% CI [0.08, 0.50]) and CRMPA (β = 0.08, 95% CI [0.03, 0.15]) indirectly influenced MVPA through AM, with SS having a greater effect than CRMPA. However, the direct effect of SS on MVPA was not significant (β = 0.07, 95% CI [-0.22, 0.30]). In boys, SS had a direct effect on both MVPA (β = 0.27, 95% CI [0.03, 0.51]) and AM (β = 0.79, 95% CI [0.65, 0.89]). For both genders, no statistically significant effects of SE and CE on MVPA were observed.

conclusionsThe findings identify SS as a prominent factor associated with MVPA, particularly for boys. For girls, MVPA was influenced through AM, which appeared to be supported by both SS and CRMPA.
