TABLE 2.
Independent Variable | β Coefficient (95% CI) | P Value |
---|---|---|
Age | −0.2 (−0.4 to −0.01) | .04 |
Sex | 5.8 (2 to 10) | .002 |
Time between ACL injury and surgery | −0.1 (−0.1 to −0.02) | .006 |
Preinjury sport frequency | 5.4 (2 to 9) | .003 |
Limb symmetry index | 0.5 (0.3 to 0.6) | .001 |
Anterior−posterior laxity | −0.6 (−1.4 to 0.2) | .2 |
IKDC subjective form (symptoms/function) | 1.3 (1.1 to 1.4) | .001 |
For categorical outcomes, a positive β coefficient is associated with male sex and the “high” category of preinjury sports frequency (4–7 days/week). ACL, anterior cruciate ligament; ACL-RSI, Anterior Cruciate Ligament–Return to Sport After Injury; IKDC, International Knee Documentation Committee.
