CRP and infection: As outlined in Figure 3, when compared with preoperative indicators, postoperative infection-related biomarkers also decreased, including WBCs ((10.4 ± 6.5)×109/L vs. (5.4 ± 3.2)×109/L, P = 0.19), neutrophils ((8.9 ± 5.9)×109/L vs. (3.9 ± 3.4)×109/L, P = 0.16), CRP (82.6 ± 72.9 mg/L vs. 56.1 ± 49.8 mg/L, P = 0.55) and PCT (3.4 ± 5.3 μg/L vs. 0.3 ± 0.2 μg/L, P = 0.29).
