Regression model summary for laxity in 104 healthy knees
| Dependent variable | Adjusted R square | Unstandardized coefficients β | Standard deviation of residuals | ||
|---|---|---|---|---|---|
| Constant | Sex | Body mass | |||
| Rotational knee laxity (°) | |||||
| IR5 | 0.46 | 32.7 | 3.7 | −0.2 | 4.1 |
| ER5 | 0.59 | 51.1 | 6.4 | −0.3 | 5.5 |
| TR5 | 0.60 | 83.8 | 10.0 | −0.6 | 8.6 |
An individual score can be calculated according to the formula: Score = [Measured value − (Constant + βSex * Sex + βbodymass * bodymass)]/Standard deviation of residuals. Sex is coded as zero for males and one for females, and body mass is expressed in kg
