Associations of body morphology and body composition with swimming performance in male and female youth swimmers: an exploratory cross-sectional study.

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: To investigate the associations of body morphology and body composition with swimming performance in male and female provincial youth swimmers. Methods: This cross-sectional study included 49 swimmers: 25 males (FINA points: 582 ± 66; age: 12.5 ± 0.7 years; height: 162.3 ± 6.6 cm; weight: 47.4 ± 6.9 kg) and 24 females (FINA points: 620 ± 84; age: 11.8 ± 0.8 years; height: 156.4 ± 6.1 cm; weight: 43.5 ± 5.1 kg). Competitive performance was represented by each swimmer's highest FINA point score. BMI, body proportions, body fat percentage, and hand and foot areas were assessed. Sex-stratified correlation and exploratory regression analyses were performed with false discovery rate correction and formal interaction testing. Results: Among female swimmers, FINA points were positively correlated with age, BMI, hand area, and foot area after FDR correction, whereas no corrected associations were observed among males. In the primary adjusted female model, hand area remained positively associated with FINA points; however, this estimate was attenuated after influential observations were excluded (β = 0.370, p = 0.052). Neither the sex × BMI nor the sex × hand area interaction was significant. Conclusion: In this exploratory sample, hand area showed a positive adjusted association with FINA points among female swimmers, but the estimate was sensitive to influential observations. These findings are hypothesis-generating and require confirmation in larger independent samples.
