Are you thinking that the placebo arm was taking both crestor and lipitor at the same time??? I do not believe that is the case...my understanding is that the placebo arm was ~1,200 patitients in total, with about 600 on crestor and 600 on lipitor.....I'm 99.99999% certain BDZ and others will confirm that no patients were taking both lipitor and crestor together.
