Receiver operator characteristic analysis of NHP ST-246 treatment using exposure levels as the cutoff parameter. ROC analysis of NHP treatments versus survival outcome versus the exposure determined that exposure equal to or greater than 0.50 mg · h/(liters/kg) was the cutoff value for survival for the 67 NHPs with sensitivity and specificity values of 92.86% and 97.44%, respectively. The ROC tree shows the number of NHPs in the analysis, along with the number of NHPs that died in the two groups.
