Hi, I currently work on a new project where I was requested to perform a Cochrane Armitage trend test across adverse events severity grades between two arms. My data consists of variables: Category, MedDRA_Term, arm, sev1, sev2, sev3, sev4 ; where sev1-sev4 correspond to ae_severity and include the number of subjects (please refer to attached document) Does anybody know how I can edit my dataset in order to perform the test? I would need to combine sev1-sev4 into one variable to use the code below? proc freq data=mydata; tables arm*severity / trend measures cl exact trend / maxtime=60; run; I would really appreciate any input from you! Many thanks, Eve
