ELISA-determined preoperative (preop) and postoperative CXCL16 levels of plasma and wound fluid levels of colorectal cancer patients. CXCL16 levels are presented as medians with 95% CI *preop vs. POD 1 (n = 23), preop vs. POD 3 (n = 14), preop vs. POD 7–13(n = 10) p = < 0.0001; preop vs. POD 14–20 (n = 4) ns, plasma vs. wound fluid (WFS); ^ρPOD1 (plasma, n = 23) vs. POD1 (WFS, n = 22); POD3 (plasma, n = 14) vs. POD3 (WFS, n = 17); POD7–13 (plasma, n = 10) vs. POD7–13 (WFS, n = 15), p < 0.0001; ^ρρPOD14–20 (plasma, n = 4) vs. POD14–20 (WFS, n = 7), p = 0.006
