ABSTRACT
Consider an experiment or study where entry of subjects is staggered over time. We are interested in a survival or “time to event” response, measured from entry into the trial. The subjects are followed for a certain duration until their event time is observed or censored. The situation is depicted in Figure 29.1 with the horizontal lines in the diagram representing
FIGURE 29.1 Accrual and follow-up in a survival study.
