From: Bimodal mortality dynamics for uveal melanoma: a cue for metastasis development traits?
Cause-specific hazard rate estimates for mortality in 578 patients treated at the Moorfields Eye Hospital between 1949 and 1972 for Choroid 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.
