Comparison of AUCs for GV indices for predicting TBR ≥ 1% in receiver-operating characteristic curve analyses. The Figure shows the comparison of AUCs for glycemic variability indices for predicting TBR ≥ 1% in receiver-operating characteristic curve analyses for CV (a), SD (b), and MAGE (c). For CV, the cutoff point was 28.4 (AUC = 0.86; 95% CI 0.79–0.91). For SD, the cutoff point was 43.0 (AUC = 0.65; 95% CI 0.55–0.74). For MAGE, the cutoff point was 113.7 (AUC = 0.66; 95% CI 0.56–0.75). AUC area under the receiver-operating characteristic curve, TBR time below target glucose range, CV coefficient of variation, SD standard deviation, MAGE mean amplitude of glycemic excursions
