Role of Alcohol in the Progression of Liver Disease Caused By Hepatitis C Virus Infection

Fig. 3. Receiver operating characteristic curve for the stepwise logistic regression model. With a cutoff of 0.5, the model has a sensitivity of 52% and a specificity of 96%. The area under the curve is 0.8205. (A model that generates false positives at the same rate as false negatives has no diagnostic usefulness, and its graph is close to a 45% line.)
