Receiver Operating Characteristics (ROC) curve parameters for the 9 novel AD miRNA biomarker candidates and 6 previously reported miRNAs that separate all early and later stage AD patients versus all non-demented controls: AD vs CTR (AD1 and AD2 vs CTR1 and CTR2) and MCI-AD vs CTR (MCI-AD1 and MCI-AD2 vs CTR1 and CTR2). The gene discussed is APP; the disease is Alzheimer disease.
