Differences between injured and uninjured legs are presented for the total cohort, as well as for handball and football players separately, adjusted for dependencies between legs. Data are shown as means with SDs.
*Data were normalised for player height (Good Balance) or leg length (Star Excursion Balance Test).
AP, anterior–posterior; ML, mediolateral.
