Cause-specific hazard rate estimates for mortality in patients undergoing eye enucleation for uveal melanoma. Blue line: data on 2105 patients from the McLean series. Red line: data on 250 patients from Benjamin series. Time-origin is at surgery. (Upper panel) Smoothed curves are obtained by a Kernel-like smoothing procedure. Standard deviation estimates for single points are also reported. (Lower panel) Hazard rates obtained by the piecewise exponential regression model. Vertical lines represent 95% point-wise confidence intervals.
