Correlations between serum C4b, PEPD and some biochemical parameters. A P-value of less than 0.05 indicates statistical significance using the Spearman correlation method. The range of rs from −0.3 to −0.1 or from 0.1 to 0.3 means weak correlation, while the range from −0.5 to −0.3 or from 0.3 to 0.5 means moderate correlation. A: correlation of C4b and albumin; B: correlation of C4b and globulin; C: correlation of C4b and C-reactive protein; D: correlation of C4b and prealbumin; E: correlation of C4b and PEPD; F: correlation of PEPD and C-reactive protein.
