Notes: – indicates that there was no significant correlation between this factor and NT-proBNP in multivariate analysis, so the standard beta value and P-value were not indicated.
Abbreviations: NT-proBNP, N-terminal pro-brain natriuretic peptide; r, correlation coefficient; β, regression coefficient; HNT, hypertension; DM, diabetes mellitus; BMI, body mass index; SBP, systolic blood pressure; DBP, diastolic blood pressure; TG, triglyceride; LDL-C, low-density lipoprotein cholesterol; FBG, fasting blood glucose; PBG, postprandial blood glucose; UA, uric acid; HCY, homocysteine; Hs-CRP, high-sensitive C-reactive protein; eGFR, estimated glomerular filtration rate.
