Maybe not a clear enough statement. I mean to say that we may not see 100% of patients respond identically to A2-73 w/PDD trial criteria. I expect some distribution from great(back to normal) to others show a more limited response however (only limited control vs back to normal) on muscle control criteria for example. So, nominally positive in this context means on net results are all positive, some more than others. A distribution of results against normalized trial criteria.
