(a) The importance of glycaemic variability in type 1 diabetes: (a) the correlation of glycaemic variability, measured as standard deviation of SMBG tests, and HbA_1c achieved during MDI (r = 0.60, p = 0.017). (From Pickup JC, Kidd J, Burmiston S, Yemane N. Determinants of glycaemic control in type 1 diabetes during intensified therapy with multiple daily insulin injections or continuous subcutaneous insulin infusion: importance of blood glucose variability. Diab Metab Res Rev, 2006; 22: 232–7 (13).) (b) The importance of glycaemic variability in type 1 diabetes: (b) the correlation of glycaemic variability, measured as coefficient of variation, and the frequency of hypoglycaemia (percentage of SMBG tests <3.5 mmol/l); r = 0.43, p = 0.01).
