Figure 3.

Cause-specific hazard rate estimates for recurrence following IBTR diagnosis and surgical treatment by time interval from initial surgery to IBTR. The hazard rate curves (time origin at surgery for IBTR) are assessed for all patients with IBTR and for patients with time to IBTR exceeding 1, 2.5 or 3 years. A. Hazard rate within a six month interval. Smoothed curves obtained by a Kernel-like smoothing procedure. B. One month basis hazard rate obtained by the formal regression approach described in the Methods section. Vertical lines represent 95% point-wise confidence interval
