I want to compare the BMI change between people with and without disease. I have cases and their matched controls, matching by age and sex.
How could I take the matching pair into account in the proc mixed?
proc mixed data = data;
class t ;
model edss_score = follow_up_year follow_up_year*edu_self_report_3g edu_self_report_3g ;
repeated t/ type= vc subject=study_id r rcorr;
random intercept follow_up_year/type= vc subject=study_id ;
run;
