  • Data are n (%), mean±SD or median (IQR).

  • To convert HbA1c value in % to mmol/mol=10.93 × %HbA1c value − 23.5), BG value in mg/dlL to mmol/L=BG mg/dL value / 18.

  • DM, diabetes mellitus;BG, blood glucose; GLP-1, Glucagon-like peptide 1; OAD, Oral antidiabetic drug; SSI, sliding scale insulin.
