(a) Serum C3 concentration between LN SLE patients and non-LN SLE patients. (b) Serum C4 concentration between LN SLE patients and non-LN SLE patients. (c) Concentration of serum anti-dsDNA between LN SLE patients and non-LN SLE patients. (d) Concentration of serum antinuclear antibody between LN SLE patients and non-LN SLE patients. value by Student’s -test. Data presents as the mean ± SEM in each group. NS: no statistical difference.
