Health of Collegiate Athletes - An Investigation into Symptoms Associated with Low Energy Availability.
Article in International journal of exercise science, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Chronic low energy availability (LEA) describes inadequate energy intake relative to expenditure and underlies Relative Energy Deficiency in Sport (REDs), impairing physiological health and athletic performance. This study examined relationships between both anthropometry and body composition, cardiovascular function, and sleep quality in collegiate athletes with LEA-associated symptoms. A total of 109 collegiate athletes (Males = 43, females = 66) underwent anthropometric analysis (BOD POD), resting cardiovascular assessment, and Pittsburgh Sleep Quality Index (PSQI) questionnaire. Mann-Whitney U-tests assessed sex differences in cardiovascular function, anthropometry, and sleep quality. Spearman rank correlations (ρ) evaluated associations between anthropometric indices and cardiovascular and sleep outcomes. Males exhibited greater anthropometric measures (p < 0.01) and blood pressure (p < 0.001) than females. Global PSQI scores indicated poor sleep quality in both sexes (males: 5.9 ± 2.7; females: 5.7 ± 2.4), with no significant sex differences. In females, anthropometry was positively correlated with blood pressure (p < 0.01). In males, greater anthropometric measures were positively associated with blood pressure and resting heart rate (p < 0.05). Of the population studied, 19% of males and 29% of females presented with a clinically low %BF; 49% of males and 47% of females had bradycardia; 16% of males and 55% of females had hypotension; and 67% of males and 62% of females had poor sleep quality. Symptoms associated with LEA are prevalent in male and female collegiate athletes and suggest the need for closer monitoring to ensure athletes optimal health and performance.
