Fig. 4From: Modeling the covariates effects on the hazard function by piecewise exponential artificial neural networks: an application to a controlled clinical trial on renal carcinomaLog hazard ratios for the two treatments by lymph nodes and pathologic T stage. Adjusted log hazard ratios estimates for interferon (solid lines) and control (dashed lines) cross-classifying by lymph nodes and pathologic T stage. The reference log HR = 0 (thin greyline) is also reported.Back to article page
