NPPB and familial dilated cardiomyopathy: For completeness, diagnostic performance metrics for NT-proBNP, individual miRNAs, and combined models in the full DCM cohort are provided in Additional file 3: Table S14, showing the increased performance of NT-proBNP on the full DCM cohort (AUC 0.926), but that integration with miRNAs still yielded significant incremental gains.
