Table 2 Comparisons of GV indices and CGM measurements between two groups (TBR ≥ 1% and < 1%)

From: The association between hypoglycemia and glycemic variability in elderly patients with type 2 diabetes: a prospective observational study

TBR (%) 0.2 (0.0, 2.1) 4.8 (2.2, 14.1) 0 (0.0, 0.2) < 0.0001
  1. Values are expressed as median (interquartile range) in each category. The Mann–Whitney U-test was used for comparisons of the parameters between the TBR ≥ 1% group and TBR < 1% group
  2. CGM continuous glucose monitoring, CV coefficient of variation, GV glycemic variability, SD standard deviation, MAGE mean amplitude of glycemic excursions, TIR time in target glucose range, TAR time above target glucose range, TBR time below target glucose range
