The great live and move challenge and the promotion of physical activity in children: results from a two-school-year cluster-randomized trial.

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
backgroundPopulation surveys indicate that a large proportion of children worldwide do not meet the recommended 60 min of moderate-to-vigorous physical activity (PA) daily. This study aimed to assess the impact of the Great Live and Move Challenge (GLMC), a theory of planned behavior (TPB)-based intervention, on PA and TPB variables in French primary school children over two school years. Secondary objectives included assessing whether TPB variables mediated the GLMC's impact on PA and whether the GLMC impacted the strength of the link between TPB variables.
methodsA cluster-randomized controlled trial was conducted over 16 months. One hundred primary schools were randomized into an intervention or control group. A total of 2723 children aged 7-11 years (mean age: 9.1; 49.7% boys) were included (n intervention = 1420, n control = 1303). The GLMC, based on TPB, comprised a motivational phase (targeting attitudes, subjective norms, and perceived behavioral control) and a volitional phase (notably focusing on the intentions-PA link). The intervention involved teachers, parents, and community stakeholders. The primary outcome was the change in the proportion of children meeting PA guidelines after 16 months. Secondary outcomes included changes in mean daily PA and TPB variables. Assessments occurred at baseline, 4, 12, and 16 months. Data were analyzed using mixed models and path analyses.
resultsThe "time × group" interaction indicated that, compared with the control group, the intervention group had a significantly higher proportion of children meeting international PA guidelines after 16 months (OR = 3.38, 95% CI = 2.50 to 4.56, P < 0.001). TPB variables did not significantly mediate the impact of the GLMC on mean daily PA at 16 months. The path coefficient between intentions and mean daily PA was significantly higher in the intervention group than in the control group at 4 (CR = 2.45; β = 0.22 vs. 0.13) and 16 months (CR = 2.87; β = 0.24 vs. 0.14).
conclusionsThe GLMC increased the proportion of children meeting PA guidelines over 16 months, and may help bridge the intentions-PA gap. The absence of mediation by TPB variables highlights the need to investigate other psychosocial mechanisms to better understand how the GLMC promotes PA in children.
