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
Insufficient physical activity (PA) among children has become a major global public health concern. The family environment plays a crucial role in shaping children's weekend PA, yet evidence-based interventions in this context remain scarce This study will conduct a three-arm cluster randomised controlled trial, 'WeekendGo!' guided by an integrated theoretical framework that encompasses the Social Cognitive Theory, Health Action Process Approach and Family Functioning Theory, aimed at promoting children's weekend PA. Approximately 555 children and their parents will be recruited and randomised into three groups: a staged intervention group (intervention I), a general intervention group (intervention II) and a control group, for 12 months. The primary outcome will be the children's weekend moderate-to-vigorous PA. Secondary outcomes will include children's cognitive factors such as self-efficacy, perceived barriers and resources, motivation and behavioural intention. Generalised linear mixed-effects models will be used for analysis, adhering to the intention-to-treat principle, with missing data handled through multiple imputation. Trial registration number: ChiCTR2500095942.
