NPPB and hydrops fetalis: As reported in Figure 3D–F, we found that the downregulation of miR-10b-5p, miR-19a-5p, and miR-1-3 was significant (p ≤ 0.01) only in HF patients with pathological NT-proBNP values (≥125 pg/mL) when compared to healthy subjects, although miR-10b-5p was also weakly downregulated (p ≤ 0.05) in patients with NT-proBNP < 125 pg/mL in comparison to healthy subjects.
