Fluid balance in the ARB + hANP and ARNI + hANP groups. A Adjusted fluid balance in the ARB + hANP and ARNI + hANP groups before PS matching. B Adjusted fluid balance in the ARB + hANP and ARNI + hANP groups after PS matching. Adjusted fluid balance was calculated as follows: In-volume (mL/day) – OUT-volume (mL/day) /daily hANP dosage. ARB, angiotensin II receptor blockers; ARNI, angiotensin receptor neprilysin inhibitor; hANP, human atrial natriuretic peptide; PS, propensity score
