id: participant ID number
def: indicator that the participant was assigned to the Deferred treatment arm
imm: indicator that the participant was assigned to the Immediate treatment arm
censyrs: censoring time, in years, corresponding to the close of study minus the time of entry for each participant
xo: an indicator that crossover occurred
xoyrs: the time, in years, from entry to switching, or 0 for participants in the Immediate arm
prog: an indicator of disease progression (1), or censoring (0)
progyrs: time, in years, from entry to disease progression or censoring
entry: the time of entry into the study, measured in years from the date of randomisation
