Prognostic role of Ki-67 in colorectal carcinoma: Development and evaluation of machine learning prediction models

Figure 3 Kaplan-Meier survival curves for colorectal carcinoma patients stratified by Ki-67 40%, 50%, 60%, and 70%. Data from the external validation dataset (208 colorectal carcinoma patients from the Yulin Red Cross Hospital). A: Ki-67 < 40% vs Ki-67 ≥ 40% Kaplan-Meier analysis with log-rank test: P = 0.3490, hazard ratio (HR) = 1.451; B: Ki-67 < 50% vs Ki-67 ≥ 50% Kaplan-Meier analysis with log-rank test: P = 0.0299, HR = 2.142; C: Ki-67 < 60% vs Ki-67 ≥ 60% Kaplan-Meier analysis with log-rank test: P = 0.4259, HR = 1.400; D: Ki-67 < 70% vs Ki-67 ≥ 70% Kaplan-Meier analysis with log-rank test: P = 0.2614, HR = 2.026. HR: Hazard ratio.
