|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|
|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.
