FIGURE 2.

Preoperative Inflammatory Burden Index (IBI) was significantly higher in colorectal cancer (CRC) patients with postoperative infectious complications. Preoperative IBI was significantly higher in patients with surgical site infection (p = 0.008) (A) and its subcategories, incisional surgical site infection (B) and organ space surgical site infection (both p = 0.03) (C). Despite no significant correlation with anastomotic leakage (D), preoperative IBI was significantly elevated for remote infection (p = 0.03) (E), and a correlation was observed for total infection (p = 0.0003) (F), which included all complications related to infections. All statistical tests were two‐sided.
