I am trying to include survival data for subjects for which the date of treatment to the abstraction date is <365 days (e.g. group X for this example). When mixed with subjects for which the date of treatment to the abstraction date is ≥ 365 the survival curve will drop as all of the group X subjects will show as failures. I have seen survival reports that include subjects that had less than the 365 days from treatment and they show as marks in the survival curve for those with treatment ≥ 365 days. Not sure what software was used to do that but would like to know if this if feasible with JMP.
