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

This study examined the effects of regular plyometric exercise on growth hormones, appetite hormones, myokines, and adipokines in adolescents with obesity and leptin resistance. Sixty adolescents (male: 11.9 ± 0.8 years; female: 13.0 ± 1.0 years) with body fat ≥ 30% and leptin ≥ 30 ng/mL participated between July 2023 and October 2024 following IRB approval. Participants were randomized by gender into control or exercise groups (n = 15 per gender). The exercise group completed a 12-week program (3 sessions/week, 150 min/week). Twelve participants withdrew (CON, n = 6; PE, n = 6). Thus, 48 participants completed the study and were included in the final per-protocol analysis. Assessments included body composition, muscle fitness (grip strength, isokinetic torque), and blood biomarkers. Significant improvements were observed in height, muscle mass, fat mass, body fat percentage, BMI, and muscle fitness in the exercise group (p < 0.05). GH and IGF-1 increased, with reduced myostatin and elevated follistatin (p < 0.05). Leptin sensitivity improved with increased adiponectin (p < 0.05). TNF-α showed no significant change. Findings suggest that plyometric exercise is an effective non-pharmacological approach to enhance growth, body composition, muscle fitness, and endocrine regulation in adolescents with obesity and leptin resistance.
