• Sensitivity = 88.3% (83/94)*100; Specificity = 83.3% (185/222)*100

• True Positive = 83; False Positive = 37; True Negative = 185; False Negative = 11

• Positive Predictive Value (PPV) = 83/120 = 68.3%

• Negative Predictive Value (NPV) = 11/196 = 5.6%

• Positive Likelihood Ratio = Sensitivity/(1–Specificity) = (0.88)/(1-0.83) = 5.18

• Negative Likelihood Ratio = (1–Sensitivity)/Specificity = (1-0.88)/0.83 = 0.14
