The data are presented either as percentage of patients showing the feature or means (95% CIs).

*p Value indicates the differences between patients with and without diabetes.

†p Value indicates the differences between the patients with and without postprandial hyperglycaemia within patients without diabetes.

BMI, body mass index; CRP, C reactive protein; HbA1c, glycosylated haemoglobin A1c expressed as percentage of total haemoglobin; NT-proBNP, plasma N-terminal proB-type natriuretic peptide.
