Hello. In my study, patients came to the doctor 3 times. At each visit, it was assessed whether the patient was taking a certain class of drugs (yes / no), a total of 7 drug classes. I need to find out if their therapy differed at visits (i.e., for example, drug A was taken more often at visit 1 than at visit 2). What test do I need to apply for this dichotomous variables in three visits? ANOVA?
Dr Rahul Panwar
The three-way repeated measures ANOVA isThis is a method to establish whether there is a significant interaction between three factors specific to each subject, and how they impact a continuous variable. (i.e. if a three-way interaction exists).
