We have expanded Chapter 1 to clarify the distinction
between random, independent, and noninformative censoring assumptions often made about survival data. We
also added a section in Chapter 1 that introduces the
Counting Process data layout that is discussed in later
chapters (3, 6, and 8).
We added sections in Chapter 2 to describe how to obtain
confidence intervals for the Kaplan–Meier (KM) curve and
the median survival time obtained from a KM curve.
We have expanded Chapter 3 on the Cox Proportional
Hazards (PH) Model by describing the use of age as the
time scale instead of time-on-follow-up as the outcome
variable. We also added a section that clarifies how to
obtain confidence intervals for PH models that contain
product terms that reflect effect modification of exposure
variables of interest
