Change of HbA1c reporting to the new SI units

In reply: We appreciate Craig and colleagues’ comments regarding the importance of reporting general HbA1c targets for children and adolescents with type 1 and type 2 diabetes. In our position statement, the headings of Box 2 and Box 3 indicated that the targets listed were for adults with type 1 diabetes and adults with type 2 diabetes, respectively.1 While it is not possible to highlight every clinical situation, we agree that providing general HbA1c targets for children and adolescents will add value to our article, and we have updated it accordingly,1 recognising the differences in these targets for type 1 diabetes (≤ 58 mmol/mol, ≤ 7.5%) and type 2 diabetes (≤ 53 mmol/mol, ≤ 7.0%).2-4 In the interests of uniformity and simplicity, the paediatric targets expressed as “<”2-4 have been adjusted to “≤”, which represents differences of less than 1.5% of the target values.
