Prevalence of Overweight and Obesity and Their Associated Factors Among Adolescent Children in an Urban School in Tamil Nadu.
Article in Cureus, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 among adolescents have emerged as major public health concerns, particularly in urban India, due to rapid lifestyle transitions, unhealthy dietary practices, and increased sedentary behavior. Adolescence is a critical period during which excess weight often tracks into adulthood, increasing the risk of non-communicable diseases. However, city-specific data from metropolitan areas such as Chennai remain limited. Methods A school-based cross-sectional study was conducted from January 2025 to April 2025 among 222 adolescents aged 13-18 years in Chennai, Tamil Nadu. Data on socio-demographic characteristics and lifestyle behaviors were collected using a pre-tested structured questionnaire. Anthropometric measurements were recorded using standard procedures, and body mass index (BMI) was calculated and classified according to WHO BMI-for-age Z-scores (5-19 years). Associations were assessed using chi-square tests and odds ratios with 95% confidence intervals, followed by multivariate logistic regression to identify independent predictors. Results A total of 222 adolescents were included in the study.
