Multivariate stepwise regression analysis with glycated hemoglobin as the dependent variable, and age, sex, body mass index, mean glucose level, standard deviation (SD), mean amplitude of glycemic excursions (MAGE), maximum glucose levels, minimum glucose levels, area under the blood concentration–time curve (AUC) >180 mg/dL, percentage of AUC >180 mg/dL, area over the blood concentration–time curve (AOC) <70 mg/dL, percentage of AOC <70 mg/dL, pre‐meal glucose level (breakfast), pre‐meal glucose level (lunch), pre‐meal glucose level (dinner), postprandial peak glucose (breakfast), postprandial peak glucose (lunch), postprandial peak glucose (dinner) as the independent variables. All variables were measured by the continuous glucose monitoring system.
