Fig. 6From: 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 applicationThe relationship between FIB and log(λ) in small cell lung cancer data. The black solid line is the estimated log relative hazard of FIB by Cox model with P-spline, the grey dashed lines present 95% confidence interval of the estimated log relative hazardBack to article page
