A: Predictive ability of this model was appraised with an area under the curve of 0.947, sensitivity of 75.92%, and specificity of 95.81%; B: Discrimination of the validated model was estimated with an area under the curve of 0.937, sensitivity of 67.31%, and specificity of 97.55%. Sens: Sensitivity; Spec: Specificity; PPV: Positive predictive value; NPV: Negative predictive value.
