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
The study aimed to investigate the reliability, construct, and discriminant validity of the Behavioral Regulation in Exercise Questionnaire 3 (BREQ-3) for evaluating motivational regulations and self-determination for exercise in Brazilian adults aged 50 years or older. The study assessed motivation for exercise, peripheral muscle strength, physical performance, functional capacity, cardiovascular fitness, and frailty phenotype. Two raters independently applied the BREQ-3. The reliability was evaluated using internal consistency, test-retest reliability, and agreement. Construct validity was tested with Spearman's correlation coefficient and discriminant validity with the Kruskal-Wallis test. Eighty individuals participated in the reliability study, and 136 participated in the validation study. Motivational regulation and Self-Determination Index (SDI) internal consistency ranged from 0.55 to 0.82. Test-retest reliability ranged from 0.77 (95% CI 0.64-0.85) to 0.91 (95% CI 0.85-0.94), and inter-rater ranged from 0.80 (95% CI 0.68-0.87) to 0.92 (95% CI 0.88-0.95), except for amotivation, which had poor inter-rater and test-retest reliability. Additionally, moderate to weak correlations between various types of motivation and physical function tests were found (
