TO THE EDITOR:
Collins and colleagues' article (1) is important because prediction is becoming an integral part of clinical medicine. I was gratified to note their statement that all predictions must be time-denominated (2). The authors suggest that there are only 2 types of predictions, diagnostic and prognostic, and subsume risk predictions within diagnostic predictions. I have suggested that risk is a third type of prediction (3).
Risk and diagnostic predictions differ in their targets, degrees of predictive accuracy, and time intervals. In diagnostic predictions, we wish to predict whether a person has detectable disease, the disease's time interval is ...
