Parameters included in the model that were not significant in any of the subgroups were systolic and diastolic blood pressure. The NT-proBNP values were log-transformed for this analysis.

BMI = body mass index; GFR = glomerular filtration rate; LA = left atrial; LV = left ventricular; NT-proBNP = amino-terminal pro-B-type natriuretic peptide.
