Figure 2: Kaplan–Meier survival analysis for Getis-Ord and spatial heatmap-based prognostic models. (a) Getis-Ord-based prognostic model. Blue line represents the “low-risk” patients, yellow line represents the “mid-risk” patients, and the red line represents the “high-risk” patients. (b) Spatial heatmap-based prognostic model. Blue line represents the “low-risk” patients, yellow line represents the “mid-risk” patients, and the red line represents the “high-risk” patients
