I hope everyone's doing well!
I'm working with a Cox model using a categorical (group) variable as my exposure of interest (groups446), along with other variables in the model. The main exposure (groups446) has 3 categories of patients (0, 1, 2). I've chosen one as my Reference group (2). Some of the reviewers for this manuscript are asking for direct comparison of individual groups (ex. group 0 vs. group 1, 0 vs 2, 1 vs. 2). I understand the pwcompare command provides coefficients and tests for these comparisons.
Is it valid/acceptable to run the model as originally set up include the groups of interest only? See "Groupwise" section of the code.
