The impact of community-based childhood obesity prevention interventions in Australia by socio-economic position: An individual participant data meta-analysis.
Synthesis in Pediatric obesity, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled 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.
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
introductionCommunity-based interventions (CBIs) to prevent childhood obesity show promise in reducing body mass index z-scores (zBMI). Assessing whether this approach produces equitable outcomes across socio-economic sub-groups is typically limited by inadequate sample size. This study aimed to assess the effectiveness of CBIs on zBMI and weight-related behaviours by socio-economic position (SEP).
methodsIndividual participant data meta-analysis using seven Australian childhood obesity prevention CBIs conducted between 2003 and 2022. Trials used consistent intervention approaches, objectively measured height and weight, and self- or parent-reported behaviours, and lasted 2-4 years. Area-level SEP was estimated using Australian Index of Relative Socio-economic Advantage and Disadvantage tertiles based on home or school postcodes. Multi-level linear and logistic models estimated the intervention effect on zBMI and behaviours across SEP levels.
resultsWhile zBMI scores increased across all groups, the increase was significantly greater in control compared to intervention students (difference: -0.036 [95%CI -0.065, -0.007]), among the 25 346 observations analysed. The effect of CBIs was greater in low compared to high SEP students (intervention effect difference = -0.10 [95%CI -0.18, -0.02]). DISCUSSION: Obesity prevention CBIs may have greater impacts among children from low SEP areas, potentially contributing to reducing health inequities. Further research is needed to understand barriers to improving weight-related behaviours across socio-economic groups.
