Figure 3.
Kaplan-Meier analysis of disease-free survival (DFS) according to SSI in patients with CRC. (A) DFS of patients with simple incisional SSI (P=0.278); (B) DFS of patients with simple organ/space SSI (P=0.378); (C) DFS of patients with incisional and organ/space SSI (P<0.001); (D) Patients with incisional and organ/space SSI had a significantly poorer 3-year DFS than those without any SSI, whereas neither simple incisional SSI nor simple organ/space SSI had a significant effect on DFS.
