Receiver operator characteristic (ROC) curve for the InterVA model. The figure shows the area under the receiver operator characteristic (ROC) curve for InterVA against HCOD. The area under the curve captures the relationship between the sensitivity and specificity of the InterVA method and is therefore indicative of how the method performed with respect to HCOD. The overall diagnostic measure for InterVA model was 0.82, indicating good diagnostic performance of the method. Also, the curve follows the left-hand border and then the top border of the ROC space, indicating an acceptable level of accuracy.
