Association of composite scores with radiological outcome. Correlation with changes in Larsen scores within 3 years from entering the inception cohort (n = 56) of time-averaged (a) Disease Activity Score (DAS)28 (R = 0.58, 95% confidence interval [CI] 0.37–0.73), (b) Simplified Disease Activity Index (SDAI; R = 0.59, 95% CI 0.39–0.74), and (c) Clinical Disease Activity Index (CDAI; R = 0.54, 95% CI 0.32–0.70). All correlations are significant (P < 0.0001). (d) C-rectaive protein (CRP; R = 0.28, 95% CI 0.02 to 0.51; P = 0.025).
