Controlling for age and sex, NT-proBNP was significantly associated with the following variables: duration of diabetes (r = 0.14; p<0.001), diastolic blood pressure (r = −0.09; p = 0.008), ABI (r = −0.14; p<0.001), BMI (r = 0.11; p<0.001) and cholesterol (r = −0.10; p = 0.005), but not with HbA1c, plasma glucose or systolic blood pressure (p>0.05). Here, NPPB is linked to diabetes mellitus.
