Should I put the matching variables in the description of adjustment, such as in the figure or tables? I matched two group by age, gender and other comorbidity. In the SAS COX proportional hazard model: PROC PHREG DATA=dm covs(aggregate); income (param=ref ref='0') urban (param=ref ref='4') ; MODEL time*cv(0)=income urban /risklimits; ID case_num; /* number for the same case and the corresponding matched control */ RUN; The matching variables: "age, gender, other comorbidity" and adjusted variables: " income, urban" need all put in the adjustment description in table/figure? Or explain the matching variables in the Statistical method and put the only adjusted variables in the adjustment description in table/figure. How to explain the matching model or matching method in the statistical method? The SAS code: ID or Strata? is the same for matching condition? Thanks for your help !
