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
This study aimed to assess the effect of exercise on high-sensitivity cardiac troponin T (hs-cTnT) concentrations in children and adolescents and to examine whether sex, maturational status, anthropometric characteristics, cardiorespiratory fitness, and physical activity influence the hs-cTnT response. In this trial 733 participants completed the 20-m shuttle run test. Venous blood samples were collected at rest and 3 h postexercise to determine hs-cTnT concentrations. We included 296 girls and 437 boys (12.2 ± 1.7 years; 40% girls). At baseline, 61% of participants had hs-cTnT values below the limit of detection (LoD), and 2.5% exceeded the upper reference limit (URL). Postexercise, 36% remained below LoD, while 7.5% exceeded the URL. Overall, hs-cTnT increased from baseline to 3 h postexercise in 56.2% of participants. Linear mixed-effects models showed a significant main effect of time (β = -0.42, 95% CI 0.35-0.49; p < 0.01) and no main effect of sex (p = 0.85), although a small but significant time × sex interaction was observed (β = -0.11, 95% CI -0.20 to -0.02; p = 0.021), indicating a slightly greater exercise-induced increase in girls. Additional significant time × covariate interactions were identified for maturational, anthropometric, and fitness-related variables. However, these factors together explained only a small proportion of the overall variability in hs-cTnT response. Consequently, the 20-m shuttle run test induces a significant increase in hs-cTnT concentrations in children and adolescents. Exercise-induced hs-cTnT release is common but highly heterogeneous, and is only partly explained by sex, maturational, anthropometric, and fitness-related factors, suggesting an important contribution of individual-specific determinants not captured by conventional variables.
