Multiple linear regression model predicting the three-year MRI cartilage score*
Baseline parameters Estimate SE Pr > |t|
Disease duration (years) 0.01 0.01 0.2916
Sex F (ref = M) −3.10 2.08 0.1522
Age 0.02 0.07 0.7494
DAS28CRP 0.29 1.22 0.8127
RF 2.94 1.78 0.115
HAQ score 0.75 1.57 0.6379
MRI cartilage score 0.67 0.14 0.0001

*The R2 of the total model was 0.78, indicating 78% of the variance observed in the MRI cartilage score at three years was explained by the model. DAS28, Disease Activity Score 28; HAQ, health assessment questionnaire; RF, rheumatoid factor.
