- * Study population n = 253 but individuals were excluded from analyses if at baseline they had the maximum score in a joint for either construct. † Change in the number of clinical features were − 2 to 2 as only two clinical features for the thumb were assessed at baseline (deformity, joint enlargement). Correlations presented are Spearman Rank correlation coefficients. DIP, Distal Interphalangeal joint; PIP, Proximal Interphalangeal joint; 1CMC, 1st Carpometacarpal joint
