After the study is concluded, won't they get the non-blinded (still anonymous) version? During efficacy/side-effect analysis you should definitely use only blinded data. After confirmatory statistical analysis, it seems reasonable to go over the data in an exploratory pass to possibly discover/hypothesize why/when/how the medicine works/fails/interacts. Or do they just get the aggregate report?
