Fig. 1. Future glycosylated hemoglobin (HbA1c) variability indices according to baseline cardiovascular autonomic neuropathy (CAN) severity. (A) The value of each HbA1c variability index according to the severity of CAN at baseline. (B) The percentage of the higher HbA1c variability group according to the severity of CAN at baseline. Data are expressed as the mean±standard deviation (SD). CV, coefficient of variation; Adj, adjusted. ^aP<0.05.
