It can't be a even spread across sites as early sites would have easily exceeded that and I guess some sites may have ended up with zero. I believe many sites are under one management group umbrella so they may bring 10 sites but active patients only ever at a few. that is my guess. The old averages game has many a twist and turn if you don't know the data . I am surprised if he is right at only 6 per site but maybe he has asked the question but it doesn't seem logical - I haven't asked. ACL
