Run-time strategy for data errors
Although efforts are made to create and maintain
an 'error-free' database, numerous minor logical inconsistencies may persist
during correspondence with trialists.
DD: MORTALITY
An event is taken to have occurred if:
The event date is taken as the date died.
If an event is not taken to have occurred,
the case is censored at the date last traced.
