MRI osteitis predicts cartilage damage at the wrist in RA: a three-year prospective 3T MRI study examining cartilage damage

Table 4 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
DAS28_CRP	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.
