We heard from the witnesses yesterday about the types of false negatives. Was the witness looking just at false negatives or at the types of false negatives? I understand that this is a screening process, but in the case of Vicky Phelan the retrospective slide had very clear evidence of cancer. Did the witness quantify the type of false negative, or the degree of the miss?
