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
Objective: This study explored the combined effects of tangeretin and whey protein on serum testosterone and cortisol in competitive athletes. Methods: In a double-blind,controlled trial, 24 elite sprinters were divided into two groups: an experimental group (EXP, n = 12) taking tangeretin (200 mg) and whey protein (19.8 g) daily, and a control group (CTRL, n = 12) taking only whey protein (19.8 g) over four weeks. Weekly and post-intervention tests measured serum testosterone, cortisol, superoxide dismutase (SOD) activity, and adrenocorticotropic hormone (ACTH) levels, along with pre- and post-intervention anthropometric assessments. Results: After intervention, a significant Time × Group interaction was observed for fat-free mass (FFM), which increased significantly in the EXP but not in the CTRL, with a greater percentage increase in EXP (2.3 % vs. 1.1 %, p = 0.018). Similar interactions were found for fat mass and body fat percentage, which decreased significantly in EXP. For biochemical indicators, no significant Group × Time interactions were found. However, a significant main effect of time was identified for serum testosterone and ACTH, indicating comparable temporal changes in both groups. No significant time or interaction effects were observed for cortisol, T/C ratio and SOD. Conclusion: Four weeks of combined whey protein and tangeretin supplementation significantly improved body composition in elite sprinters, whereas it did not significantly alter systemic hormonal profiles or antioxidant activity compared to whey protein alone.
