Dear Statalist friends,
I'm simulating a study which I originally thought was an AB-BA
crossover design, but the more I contemplate the analysis, the more it
seems I have a three-treatment design. The study calendar is as follows:
4 week washout > randomize to A or B > 4 week washout > switch A & B
During the washout period, patients receive "standard care".
I wish to compare:
Standard care to A
Standard care to B
A to B
Would this then be analyzed as a series of 3 separate pkcross
statements?
Best wishes,
Michael McCulloch
