Fig. 1From: Modeling the covariates effects on the hazard function by piecewise exponential artificial neural networks: an application to a controlled clinical trial on renal carcinomaHazards and log hazard ratio for the two treatments. Left panel: Adjusted hazard function estimates for interferon (solid lines) and control (dashed lines). Right panel: Adjusted log hazard ratio (solid) with 95% bootstrap confidence intervals (dotted). The reference log HR = 0 (thin grey line) is also reportedBack to article page
