Coding: n/N = number of significant associated relationships divided by total number of relationships investigated. The number of relationships is reported with the study reference number in brackets
Data removed from univariate analyses’ data synthesis due to poor methodological quality and/or high ROB included: noncontact ACL injury—coordination measures (1 relationship [71]), ankle sprain—balance measures (5 relationships [97]), body composition measures (2 relationships [97]), flexibility measures (1 relationship [97]), and power measures (1 relationship [97]). Data removed from multivariate analyses’ data synthesis due to poor methodological quality and/or high ROB included: noncontact ACL injury—balance (1 relationship [88], 1 relationship [71]), body composition measures (1 relationship [88], 2 relationships [71, 102]), coordination measures (5 relationships [71]), flexibility measures (1 relationship [88], 2 relationships [71]), muscular strength measures (3 relationships [88])
