Spearman rank correlation analysis of PGRN and inflammatory factor in SLE patients before prednisone treatment. PGRN was correlated with the levels of IL-6 (r = 0.790, P < 0.01), TNFR (r = 0.559, P = 0.01), TNF-α (r = 0.438, P = 0.015) and anti-dsDNA antibody (r = 0.906, P < 0.01) in the serum of pre-treatment SLE patients. (A) Pre-treatment, IL-6 vs PGRN; (B) Pre-treament, TNFR vs PGRN; (C) Pre-treament, TNF-α vs PGRN; (D) Pre-treament, dsDNA vs PGRN.
