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 */
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 !
