Statistical comparisons of composite FA index (knee, ankle, and foot FA combined) between athletes and controls.

Results are shown first with no covariates (F3,185 = 4.86, p = 0.003, adjusted r2 = 0.058) and then with covariates age and weight added (F5,183 = 3.46, p = 0.005, adjusted r2 = 0.061). Statistically significant relationships (two-tailed tests, alpha = 0.05) are indicated with asterisks.
