A competingrisk model is therefore not the right model analyzing recurrent events.</P><P></P><P>But, what you can do is to model the recurrent events with a Cox-model using either time since last event. You can thereby have more events per person in a Cox-model, just restart the time at each event.&nbsp; Or you can have time since beginning of trial as underlying time axis, then you should have the last timepoint as a left-truncation on the time at risk (you can find an example here: <A href="http://support.sas.com/documentation/cdl/en/statug/67523/HTML/default/viewer.htm#statug_phreg_examples10.htm" title="http://support.sas.com/documentation/cdl/en/statug/67523/HTML/default/viewer.htm#statug_phreg_examples10.htm">SAS/STAT(R) 13.2 User's Guide</A>)</P><P>The other eventtypes can be taken into account by constructing a timedependent covariate that counts numbers of the other event type.</P></BODY></HTML> Wed, 10 Dec 2014 09:08:06 GMT https://communities.sas.com/t5/Statistical-Procedures/can-phreg-modeling-with-competing-risks-be-run-with-recurrent/m-p/141720#M7384 JacobSimonsen 2014-12-10T09:08:06Z
