Model 1: Adjusted for age and sex.
Model 2: Adjusted for age, sex, cBMI, and SBP.
Model 3: Adjusted for age, sex, cBMI, SBP, calcium, eGFR, and hs-CRP.
OH/ECW tertiles 1, 2, and 3 correspond to <10.60, 10.60–24.68, and >24.68%, respectively.
NT-proBNP tertiles 1, 2, and 3 correspond to <1,143, 1,143–7,087, and >7,087 pg/mL, respectively.
B, β coefficient; cBMI, corrected body mass index; CI, confidence interval; ECW, extracellular water; eGFR, estimated glomerular filtration rate; hs-CRP, high-sensitivity C reactive protein; NT-proBNP, N-terminal prohormone B-type natriuretic peptide; OH, overhydration; SBP, systolic blood pressure.
