Ln: base e logarithm; MAGE: the 24 h mean amplitude of glycemic excursion; SDBG: the standard deviation of 24 h blood glucose; LAGE: the large amplitude of glycemic excursion; MBG: the 24 h mean blood glucose concentration; AUC > 13.9 mmol/l: the incremental area under the curve of plasma glucose > 13.9 mmol/l; AUC < 3.9 mmol/l: the incremental area under the curve of plasma glucose < 3.9 mmol/l; PT1: the percentage of the time spent on glucose concentrations above 13.9 mmol/l; PT2: the percentage of the time spent on glucose concentrations below 3.9 mmol/l. aCompared with the C group (p < 0.05); bcompared with the L group (p < 0.05); cnonparametric test. Data were presented as mean ± SD or median (25th, 75th percentile).
