Figure 2.

Cause-specific hazard rate estimates for mortality in 1317 patients from the COMS series, undergoing either I¹²⁵ brachytherapy or enucleation for unilateral choroidal melanoma. 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.
