https://communities.sas.com/t5/SAS-Programming/competing-risk/m-p/557753#M155538 <P>Hi,</P> <P>I have a survival analysis to do that involves competing risk.&nbsp; Dataset contains approximately 2500 pts, a subset of which died from either cardiac, cancer, or unknown (death=1,2,3, respectively, 0 if not dead at end of study followup).&nbsp; I need to built a model (forward selection strategy with entry and stay criterion both set at p=0.05) using proc phreg accounting for the competing risk from non-cardiac deaths.&nbsp; Then I need to add a new variable omega (serum omega-fish oil level) to see if omega level has association with death incremental to the variables in the model (e.g. var1, var2, var3).&nbsp; The death of interests is cardiac death (death=1) and I had previously censored all other deaths, which obviously did not account for the competing risk. &nbsp;</P> <P>&nbsp;</P> <P>I found many macros in the web but so far have trouble running them.&nbsp; Unfortunately my skills in using macro is limited. &nbsp; Would anyone be willing to share a solution.&nbsp; Would you be so kind to give me detail instructions if this is a macro you are sharing with me?</P> <P>&nbsp;</P> <P>much appreciated</P> Fri, 10 May 2019 12:47:04 GMT rykwong 2019-05-10T12:47:04Z https://communities.sas.com/t5/SAS-Programming/competing-risk/m-p/557753#M155538 <P>Hi,</P> <P>I have a survival analysis to do that involves competing risk.&nbsp; Dataset contains approximately 2500 pts, a subset of which died from either cardiac, cancer, or unknown (death=1,2,3, respectively, 0 if not dead at end of study followup).&nbsp; I need to built a model (forward selection strategy with entry and stay criterion both set at p=0.05) using proc phreg accounting for the competing risk from non-cardiac deaths.&nbsp; Then I need to add a new variable omega (serum omega-fish oil level) to see if omega level has association with death incremental to the variables in the model (e.g. var1, var2, var3).&nbsp; The death of interests is cardiac death (death=1) and I had previously censored all other deaths, which obviously did not account for the competing risk. &nbsp;</P> <P>&nbsp;</P> <P>I found many macros in the web but so far have trouble running them.&nbsp; Unfortunately my skills in using macro is limited. &nbsp; Would anyone be willing to share a solution.&nbsp; Would you be so kind to give me detail instructions if this is a macro you are sharing with me?</P> <P>&nbsp;</P> <P>much appreciated</P> Fri, 10 May 2019 12:47:04 GMT https://communities.sas.com/t5/SAS-Programming/competing-risk/m-p/557753#M155538 rykwong 2019-05-10T12:47:04Z https://communities.sas.com/t5/SAS-Programming/competing-risk/m-p/557820#M155560 What version of SAS do you have? If you have SAS 9.4+ PROC PHREG can now do competing risk analysis. Or are you looking for customized graphs or tests?<BR /><BR /><BR />And if you want to outsource it feel free to contact me <span class="lia-unicode-emoji" title=":winking_face:">😉</span> Fri, 10 May 2019 15:17:41 GMT https://communities.sas.com/t5/SAS-Programming/competing-risk/m-p/557820#M155560 Reeza 2019-05-10T15:17:41Z
