Model 1: multiple regression analysis of patient history and clinical examination as predictors for time to RTS after controlling for potential treatment confounders (n=180)
| Predictor for time to RTS | β-Coefficient | 95% CI | p Value |
|---|---|---|---|
| Maximum pain score (VAS) | 1.6 | 0.8 to 2.4 | <0.001 |
| Forced to stop within 5 min (yes/no*) | 5.3 | 1.9 to 8.8 | 0.003 |
| Length of hamstring tenderness (cm) | 0.7 | 0.3 to 1.1 | 0.002 |
| Painful resisted knee flexion (90°) | 4.7 | 0.03 to 9.3 | 0.048 |
Regression coefficients are presented as adjusted unstandardised β-coefficients with 95% CIs.
