Hello everyone,
I have a cohort with 1 group (no comparison group).
I created a landmark analysis with 3 periods of time (0-1 month, 1-12 months and 12-24months post-procedure) with the following syntax:
stset Followup_month, id(id) failure(V1=1)
stsplit Landmark, at(1, 12)
I am pretty happy with the aspect of the sts graph created with the variable Landmark. landmark.tif
Now I would like to compare the incidence of V1 between the periods in order to demonstrate that there are no statistical differences between them. What would be the proper test?
I assume that sts test Landmark, logrank doesn't work here.
Thank you very much.
