Risk factors for anastomotic leakage after radical colorectal cancer surgery and its impact on prognosis: Clinical education research

Figure 1 Kaplan-Meier curves for overall survival and disease-free survival in the anastomotic leakage group (n = 22) and non-anastomotic leakage group (n = 178). A: Overall survival. The Anastomotic leakage (AL) group showed significantly lower overall survival compared to the non-AL group (log-rank χ² = 8.542, P = 0.003); B: Disease-free survival. The AL group demonstrated significantly lower disease-free survival compared to the non-AL group (log-rank χ² = 10.384, P = 0.001).
