Spearman rank correlation analysis of PGRN and inflammatory factor in SLE patients after prednisone treatment. PGRN was correlated with IL-6 (r = 0.836, P < 0.01), PR3 (r = 0.396, P = 0.031), TNFR (r = 0.533, p = 0.02), TNF-α (r = 0.378, P = 0.039) and anti-dsDNA antibody (r = 0.712, P < 0.01) in post-treatment SLE patients. (A) Post-treatment, IL-6 vs PGRN; (B) Post-treament, TNFR vs PGRN; (C) Post-treament, TNF-α vs PGRN; (D) Post-treament, dsDNA vs PGRN.
