From: A novel approach to determine two optimal cut-points of a continuous predictor with a U-shaped relationship to hazard ratio in survival data: simulation and application

Fig. 1

Schematic diagram of the optimal equal-HR method. The solid black line presents the U-shaped relationship between the continuous x and log relative hazard. The red dashed line is parallel to the x-axis, which means P1 and P2 have equal log relative hazard values. The optimal equal-HR method searches pairs of cut-points with equal log relative hazard values as candidate cut-points, such as (P1, P2)
