ALB and Hypoalbuminemia: Table 4 indicates a significant increase in serum IL-1 levels in the low-protein diet group (E) (P < 0.05) compared with those in the control (A), preoperative albumin infusion (B), postoperative albumin infusion (D), and normal protein diet (C) groups. Moreover, we detected no significant differences in serum CRP levels among the hypoalbuminemia, preoperative albumin infusion (B), postoperative albumin infusion (D), and normal protein diet (C) groups (P > 0.05).
