"In stratified cox regression there are seperate reference-rates for each category of the factor that defines strata. The seperate reference-rates does not have to be proportionate. Stratification is therefore an alternative correction method that can be used for correction of categorical variables, and a method that does not prerequisite proportionality"
To me this sounds like the approach that would suit this problem of non-proportinate hazards. Can you help me understand why this is not the way to go?
by convergence you mean; "similarity of hazards/rates" or "proportionality"? I am probably misunderstanding, but isn't the puporse of doing time varying cox, to not have to "worry" about convergence/proportionality?
And for my own understanding, could you say that using the below commands, would be like making an adjusted analysis of
first, the association between stroke severity and fractures, adjusted for civil status sex age ami diabetes and alcohol intake,
and then second, civil status and fractures, adjusted for stroke severity sex age ami diabetes and alcohol intake WITHOUT having to consider the effect (modification) of time?
So the hazard ratios that i get from that output are in fact the final results?
Code:
stcox stroke_severity civil_status sex age ami diabetes alcohol_intake , tvc(i.stroke_severity) texp(_t) stcox civil_status stroke_severity sex age ami diabetes alcohol_intake , tvc(i.civil_status) texp(_t)
