Although we did not find any significant interaction between NT-proBNP and BMI with incident hypertension as outcome (P = 0.86), we performed a stratified analysis dividing the study population into two groups with BMI ≥25 kg/m2 (n = 1,271) and <25 kg/m2 (n = 1,482), because we anticipated that a low serum concentration of NT-proBNP could after all be more predictive of risk of incident hypertension in the overweight segment of our study population. Here, NPPB is linked to Hypertension.
