TPR (left-hand columns) is the probability that a dose was recommended in an efficacious DEC, i.e. a DEC having at least one dose level with sufficiently large response rate. FPR (right-hand columns) is the probability that a dose was recommended in an inefficacious DEC, i.e. a DEC having no dose levels with sufficiently large response rate.
