Association of CCN3 with disease activity in RA patients. (a) The determination of linear relationship between serum CCN3 expression and DAS28 in RA patients was performed by the Spearman correlation coefficient. (b) The RA patients were divided into inactive, moderate, and very active groups by the DAS28 (ESR) and DAS28 (CRP). Serum CCN3 levels were compared among these groups, and the difference was evaluated by the Mann-Whitney test. indicates ; indicates .
