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: Overweight and obesity are rising health concerns in South Africa, increasingly affecting young adults in rural communities, and are influenced by distinct demographic, socio-economic and behavioural factors. Aim: This study aimed to determine the prevalence of body mass index (BMI)-defined overweight and obesity among young adults aged 18-29 years. Setting: The study was conducted in Lephalale, a predominantly rural-industrial area located within the Waterberg District Municipality of Limpopo province, South Africa. Methods: A community-based cross-sectional survey of 1063 adults aged 18-29 years from 42 rural settlements collected data on socio-demographic characteristics, employment, income, government grant receipt, physical activity (International Physical Activity Questionnaire - IPAQ), dietary practices (processed and fast food intake, fruit and vegetable consumption), smoking and alcohol use. BMI was calculated as weight divided by height squared (kg/m Results: The combined prevalence of overweight and obesity was 35%. Significant independent predictors included age 25-29 years (adjusted odds ratio [AOR]: 2.05; 95% confidence interval [CI]: 1.40-3.00), government grant receipt (AOR: 1.55; 95% CI: 1.05-2.28), daily processed food intake (AOR: 1.85; 95% CI: 1.25-2.73), weekly fast food intake (AOR: 1.70; 95% CI: 1.18-2.45), smoking (AOR: 1.25; 95% CI: 1.00-1.72) and daily alcohol use (AOR: 2.10; 95% CI: 1.35-3.15). Overweight and obesity were prevalent among rural young adults and were associated with socio-economic vulnerability and modifiable lifestyle behaviours. Conclusion: Overweight and obesity were highly prevalent among young adults living in a rural-industrial setting in Limpopo province. Contribution: The findings highlight priority behavioural and social determinants that can inform targeted public health interventions and obesity-prevention policies in transitioning rural communities.
