Comparison of plasma or serum levels of C3, C4 and CH50 between inulin clearance (Cin) < 60 mL/min/1.73 m2 (Cin < 60) and Cin ≥ 60 mL/min/1.73 m2 (Cin ≥ 60). In plasma and serum samples, levels of C3, C4 and CH50 did not differ significantly between Cin < 60 and Cin ≥ 60. a and d, b and e, and c and f show levels of C3, C4 and CH50, respectively. a–c and d–f show plasma and serum samples, respectively. Closed and open circles represent Cin < 60 and Cin ≥ 60, respectively
