Visualization of the event generation models. White cells correspond to the control condition and grey cells to the intervention condition. Cross marks indicate when a subject enters the trial, filled black circles indicate relapse, and filled white circles indicate censoring. a Example of the Poisson process and the Mixed-Poisson process: all three time-to-events occur at the time of trial entry. b Example of the Weibull model: the first time-to-event occurs at the time of trial entry, and the second and subsequent time-to-events occur at the time of the previous event
