Moreover, the rate of HF-related rehospitalization (RR, 0.63; 95% CI, 0.40-0.99) and N-terminal pro-B-type natriuretic peptide (NT-proBNP) concentration (standardized mean difference, -2.28; 95% CI, -4.34 to -0.22) were markedly lower in the LUS-guided treatment group. The gene discussed is NPPB; the disease is hydrops fetalis.
