Dear colleges,
I am now making a survival analysis using the multi-record data.
Now, I want to restrict the subjects for analysis regarding their life
styles.
>> e.g. make analysis only among subjects who are smokers (smoke==1) at
the time of the baseline(_t0==0).
>> e.g. make analysis only among subjects who are smokers at the time of
the endpoint.
In this case what command should be used to restrict the subjects?
Thank you.
