Dear all,

I would like to ask for some advice on 'stset'-ing my dataset with multiple failures per patient.

I have set up my data as recommended by the 'Cleves' tutorial but when I stset, it only recognises the first line per 'subjectid' & I get single-failure-per-subject-data, with blank cells for the subsequent rows.


Variables:

subjectid / tstart / tstop / status /

Command:

stset tstop, failure(status) id("subjectid") enter(tstart) exit(tstop)


id: subjectid
failure event: admission != 0 & admission < .
obs. time interval: (tstop[_n-1], tstop]
enter on or after: time tstart
exit on or before: time tstop

------------------------------------------------------------------------------
3,619 total observations
9 observations end on or before enter()
1,969 observations begin on or after exit
------------------------------------------------------------------------------
1,641 observations remaining, representing
1,641 subjects
833 failures in single-failure-per-subject data
1,190,569 total analysis time at risk and under observation
at risk from t = 0
earliest observed entry t = 0
last observed exit t = 1,581


Variations of the command (including addition of: time0(tstart)) don't seem to help.
Any help would be gratefully received. Thank you
