LINC-PINT and bipolar disorder: The criterion values (cutoff values) of lincRNA-p21, lncRNA-ROR and lincRNA-PINT were 4.30, 5.10 and 1.56 respectively. According to AUC (area under curve) values, all lncRNAs, particularly lncRNA-ROR (sensitivity = 86% and specificity = 73%) can be used as diagnostic biomarkers in bipolar disorder.
