The authors found errors in Table 1 after publication of the original article [1].
The correct values for medical history of coronary artery disease (CAD) at baseline are 110 (40%) of all patients, 54(35.5%) of patients categorized as having normoglycaemia, 42(46.7%) of patients categorized as having intermediate hyperglycaemia, and 14 (42.4%) of patients categorized as having DM.
All presented numbers and calculations in Table 1 are checked. No other errors were found. The presented errors did not affect results, scientific content or conclusions.
