When a referral is involved, there are three parties: the patient, of course, and the doctor or medical practice to whom the patient is sent, and the doctor or medical practice sending the patient. I would say that the doctors administering the folinic acid are not the same doctors who prescribed the other regimen. That regimen was prescribed before the folinic acid doctors evaluated the patients who had been referred to them. The word
preevaluation is spoken from the perspective of the folinic acid doctors: it means before they did their evaluation. —
