Description
This flag is generated by the program that creates Surv-Mos Presumed Alive [1787] and describes how complete the date information is that was used to calculate survival months. This item is one of seven survival variables designed to facilitate a common approach to survival analysis by NAACCR registries.
Rationale
The flag will enable analysts to easily select a subset of cases.
