COMP-C3b in SLE patients. Comparison of serum COMP-C3b (a) and COMP (b) in systemic lupus erythematosus (SLE) patients during remission (n = 30) and flare (n = 26). SLE patients with arthritis during flare (n = 11) have higher COMP-C3b than do patients without arthritis during flare (n = 15) (c). Correlation between COMP-C3b and C1q (d), C4 (e), C3 (f) in SLE patients during flare was measured by using the Spearman correlation analysis.
