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/
objectivesDespite global efforts to promote moderate-to-vigorous physical activity (MVPA) among youth, limited evidence exists regarding adolescents' knowledge of official physical activity (PA) guidelines. The aim of this study was to assess adolescents' knowledge of MVPA guidelines and examine its potential association with meeting PA recommendations and levels of sedentary behavior.
methodsThis cross-sectional study was conducted in 2025 with a sample of 1032 adolescents (50.5% boys) from northernmost Brazil. Data were collected using a self-administered questionnaire and included information on knowledge of PA guidelines, PA levels, sedentary behavior duration, and sociodemographic characteristics. Associations were tested using logistic regression models.
resultsOnly 11.7% of adolescents accurately identified all components of the PA recommendations. Boys who met PA guidelines were 15.76 times more likely to be aware of the official recommendations (95% CI: 7.14-24.48), while girls had 10.05 times higher odds (95% CI: 4.43-16.67). Adolescents who were less sedentary (<3 h/day) were significantly more likely to know the guidelines, both among boys (OR = 2.00; 95% CI: 1.08-3.70) and girls (OR = 3.13; 95% CI: 1.12-8.33).
conclusionsThe low level of awareness regarding official PA guidelines among adolescents is concerning, particularly given the strong association between such knowledge and the adoption of more active and less sedentary behaviors. Public health and educational strategies should prioritize health literacy in school curricula and community-based programs to promote more active lifestyles and reduce sedentary behavior among youth. Future studies should use longitudinal designs to clarify causal links and test practical interventions.
