get_time_to_event_at {vaccineff} | R Documentation |
This function returns both the time-to-event until a
reference number of days, as provided in at
, and the outcome status
at the same point. It uses the exposure time as an auxiliary variable
to calculate the time-to-event. The starting point for counting the
time-to-event is t0_follow_up
, which is determined based on whether
a matching strategy is used or not. If the event occurs before the
reference date, the end date of the exposure period is used to
calculate the time-to-event. This accounts for whether censoring or an
event occurred. The outcome status is determined based on whether the
outcome date coincides with the end of the follow-up period.
