I applied linear mixed models in Stata to have the annual rates of some variables in a some disease and compare different treatments during the follow up ( 3 time points).
strPatId: subject as random effect
I want to know individually for each treatment.
keep if treatment == A mixed variableX c.time_visit || strPatId:time_visit , var reml keep if treatment == B mixed variableX c.time_visit || strPatId:time_visit , var reml
annual rate treatment A = x /year (p<0.001) annual rate treatment B = y /year (p<0.001)
I need to understand how I can compare the coefficients of annual rates between two treatments, i.e. to say that treatment A has _____ fold (p=___) faster than treatment B.
mixed variableX c.time_visit##i.treatment || strPatId:time_visit , var reml
May I assume that i.treatment#c.time_visit result is the difference of rates comparing both coefficients?
