Correlation between serum level of PGLYRP2 and serological and renal function indexes in SLE patients. (A) Serum PGLYRP2 was significantly higher in SLE patients with low C3 level (5109.06 ± 479.70 pg/ml) than in those with normal C3 levels (4613.82 ± 588.89 pg/ml) (left side). Serum PGLYRP2 was significantly higher in SLE patients with low C4 level (5116.02 ± 531.27 pg/ml) than in those with normal C4 levels (4719.24 ± 571.00 pg/ml) (right side). (B) Serum PGLYRP2 was negatively correlated with C3 level (r = 0.5113, P < 0.01), C4 level (r = 0.4358, P < 0.01), eGFR (r = 0.4587, P < 0.01) and lgA (r = 0.4046, P < 0.01), but positively correlated with 24-h urine protein level (r = 0.5226, P < 0.01) in SLE patients
