[Diagnostic P300 threshold based on the analysis of receiver operating characteristic curve].

OBJECTIVE To explore the diagnostic application of receiver operating characteristic (ROC) curve of P300 amplitude and latency in schizophrenia. METHODS ROC curve of P300 amplitude and latency was plotted from 91 first episode schizophrenia (FES) and 141 normal controls (NC). Youden's index and distance were calculated in ROC curve to determine the… CONTINUE READING
