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
aimBody dissatisfaction and unhealthy weight control behaviours are common during adolescence. We examined associations between body image, diet, physical activity, and risk behaviours for weight control among high school students.
methodsThis cross-sectional study included 802 adolescents from five municipalities in southern Brazil, including 795 aged 14-19 years and seven aged 20 years. Data were collected between May and June 2022 using self-administered questionnaires based on the National School Health Survey. Risk behaviours were defined as vomiting, laxative use, or use of weight-loss products in the previous 30 days. Associations were analysed using Poisson regression with robust variance, adjusted for age, sex, maternal education, and socioeconomic status.
resultsThe sample included 802 adolescents, 50.0% male, with a mean age of 16.7 years (range 14-20). The prevalence of risk behaviours was 4.8%. Body dissatisfaction was associated with a higher likelihood of these behaviours (adjusted prevalence ratio 3.53, 95% confidence interval 1.65-7.53), with stronger effects among females (4.59, 1.33-15.78). No significant associations were found for diet or physical activity.
conclusionsBody dissatisfaction was associated with harmful weight control behaviours in adolescents and may support early identification and prevention strategies.
