Figure 2.

Receiver operating characteristic curve shows the effect of various parameter sets. Inset is the magnified area for better visualization. Larger dots represent various sets of parameters selected for further analysis. Aggressive set has the highest true positive rate while on the other hand; cautious set has the lowest false positive rate. Nominal set has parameters between aggressive and cautious, and the trial set was determined in the region relatively closer to the aggressive and currently being used in a clinical study.
