Impact of treatment strategy and physical performance on future knee-related self-efficacy in individuals with ACL injury

Table 3 Spearman’s rank-order correlations (r_s) and rank-order partial correlations (r_sp) between physical performance at the end of the exercise therapy and at 5 years after ACL injury/ACLR and K-SES scores at 6 years

Bold numbers represent moderate correlations. Regular numbers represent low correlations. Correlation coefficients: ≥ 0.10 to 0.29 denote low association, ≥ 0.30 to 0.49 moderate association and coefficients ≥0.50 large association
