Sample Size Estimation using the Receiver Operating Characteristic Curve [PDF]
In this paper we describe two related approaches to estimating the sample sizes required to statistically compare the performance of two classifiers: acceptable failure rates (AFR) and the area under the receiver operating characteristic (ROC) curve (AUC)

Plasma-derived phosphoglycerate mutase 5 as a biomarker for Parkinson’s disease
BackgroundWe aimed to examine whether plasma-derived phosphoglycerate mutase 5 (PGAM5) can be a biomarker for Parkinson’s disease (PD) diagnosis as well as its association with the severity of motor/non-motor manifestations of PD.MethodsWe enrolled 124 ...
