回答: RCT design to test the effectiveness of an intervention 由 cornbug 于 2012-01-13, 11:31:10:

the approach you are doing is very common in the health service research field. we don't use survival analysis, which is more appropriate in assessing survival rate for certain disease after treatment. Yes, it is called longitudinal analysis. you may find relevent papers, books, and in SAS, we use generalized linear model or mixed effect model to deal with the repeat measurement and clustering effect. Certain procedure does give identical results from ANOVA
