A competing risk analysis is used to study the impact of one or more risks on an outcome of interest, taking into account the presence of other risks that may affect the outcome. In SAS, you can use the <CODE>CRCPHREG</CODE> procedure to perform a competing risk analysis with time-dependent covariates.</P> <P>To use the <CODE>CRCPHREG</CODE> procedure, you will need to have your data organized in a specific way. First, you will need a variable that identifies each subject in your study. You will also need a time-variable that indicates the time at which the event of interest occurred or was censored. You will also need to have a variable that indicates the event type (e.g. the specific competing risk that occurred) and a variable that indicates whether the event was observed or censored.</P> <P>Once you have your data organized in this way, you can use the <CODE>CRCPHREG</CODE> procedure to fit a competing risk model. Here is an example of how you might do this in SAS:</P> <P>&nbsp;</P> <PRE><CODE class=" language-sas">PROC CRCPHREG DATA=mydata; MODEL event_time*event_type(0)=covariates; RUN; </CODE></PRE> <P>In this example, <CODE>event_time</CODE> is the time-variable, <CODE>event_type</CODE> is the variable indicating the event type, and <CODE>covariates</CODE> is a list of the covariates that you want to include in the model.</P> <P>I hope this helps! If you have any other questions, please let me know.</P> Wed, 07 Dec 2022 01:54:32 GMT https://communities.sas.com/t5/SAS-Software-for-Learning/Competing-risk-with-time-dependent-covariates/m-p/848256#M852 webart999ARM 2022-12-07T01:54:32Z https://communities.sas.com/t5/SAS-Software-for-Learning/Competing-risk-with-time-dependent-covariates/m-p/848679#M853 <P>Thanks for your quick reply. Actually, I wanted to know more about this command because I read an article about competing risks with time-dependent covariates and realized that there is some hesitation in doing this analysis. So it is better for me to know the details of this command. I surfed the net but unfortunately, I couldn't find anything about this command. Can you please help me again?</P><P>&nbsp;</P> Fri, 09 Dec 2022 02:19:17 GMT https://communities.sas.com/t5/SAS-Software-for-Learning/Competing-risk-with-time-dependent-covariates/m-p/848679#M853 arezoo 2022-12-09T02:19:17Z
