Relationship between serum IFN activity and SLEDAI-2K score before and after induction therapy. A Correlation between serum IFN activity and total score of SLEDAI-2K at baseline was assessed by Spearman’s rank-order correlation. B Changes in serum IFN activities and SLEDAI-2K scores before (1st point) and after (2nd point) the induction therapy are shown. C Correlation between changes in serum IFN activity and SLEDAI-2K score before and after induction therapy was examined by linear regression. IFN, type I interferon; SLEDAI-2K, SLE disease activity index 2000
