1 · What the graph read from 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.

2 · The registry

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: Motivation is essential in turning the intention to engage in physical activity (PA) into consistent action, promoting healthier and more sustainable habits. This study aimed to identify the motivational factors associated with engagement in a PA program and examine the relationship between motivation and body composition in adolescents with obesity. Methods: Fifty adolescents (60.0 % boys); Median age of 13.6 years (IQR: 2.4); Median BMI z-score of 3.42 (IQR: 1.55) recruited for a PA program were included in this cross-sectional study. All participants completed standardized body composition assessments and an online questionnaire assessing five motivational domains: enjoyment and competence (intrinsic), and appearance, fitness, and social (extrinsic domains). Results: Fitness emerged as the main reason for engaging in the PA program (6.41 ± 0.81), followed by appearance (5.64 ± 1.43), enjoyment (4.98 ± 1.47), competence (4.55 ± 1.99), and social (3.79 ± 1.85). Enjoyment and competence showed significant negative associations with body weight. ( Conclusion: Extrinsic motives, such as fitness and appearance may drive PA engagement in treatment-seeking adolescents with obesity. However, intrinsic motives, such as enjoyment and competence, may be inversely associated with BMI z-score. Thus, targeting both extrinsic and intrinsic motivation may help to improve adherence and weight outcomes in obesity care. More studies with larger samples are needed to confirm these findings.
