Association of the NT‐proBNP/emBNP Molar Ratio on Day 3 With Percentage Decreases in eGFR

Model	Parameter Estimate	95% CI	P Value
1	−1.504	−2.239 to −0.769	<0.001
2	−1.364	−2.156 to −0.573	<0.001
3	−1.226	−1.974 to −0.477	0.002
4	−1.504	−2.242 to −0.767	<0.001
5	−0.942	−1.800 to −0.085	0.032

Model 1, adjusted for age and sex. Model 2, adjusted for age, sex, and eGFR (day 3). Model 3, adjusted for age, sex, and total dosage of intravenous furosemide for first 3 days. Model 4, adjusted for age, sex, and systolic blood pressure (BP) on admission. Model 5, adjusted for age, sex, eGFR, total dosage of intravenous furosemide administration for first 3 days, and systolic BP on admission. eGFR indicates estimated glomerular filtration rate; emBNP, estimated mature B‐type or brain natriuretic peptide; NT‐proBNP, N‐terminal pro‐B‐type natriuretic peptide.
