Multiple stepwise regression analysis of radiological erosion score according to the Larsen method (dependent variable) and demographic and disease related variables (independent variables). The regression equation was: radiological erosion score=0.191+4.043×10−2×disease duration (years)+2.265×10−2×CRP (mg/l)

| Constant | 0.19 | ||
| β | SE | p Value | |
| β Values are unstandardised regression coefficients. The multiple R2 is equal to the variance explained in the model. SE=standard error. | |||
| CRP, C reactive protein. | |||
| Disease duration (years) | 4.04×10−2 | 0.007 | <0.001 |
| CRP (mg/l) | 2.26×10−2 | 0.005 | <0.001 |
| R 2 | 0.54 | ||
