  1. Data are means ± standard deviations, medians (interquartile ranges), or frequencies (percentages).
  2. eGFR estimated Glomerular Filtration Rate, HbA1c Hemoglobin A1c, HOMA-β Homeostasis Model Assessment of b-cell, HOMA-IR Homeostasis Model Assessment of Insulin Resistance.
  3. aData on family history of diabetes were missing in 6 patients. Matsuda’s index denotes Matsuda’s insulin sensitivity index. The insulin secretion index denotes ΔI0-120/ΔG0-120.
