  • Data are n (%) or %. To convert serum creatinine to micromoles per liter, multiply by 88.4.

  • *The study population comprised patients with diabetes and an HbA1c value available in FY 2013 who were taking any antiglycemic agent other than metformin alone within 60 days before their last HbA1c in FY 2013 and who had at least one of the studied comorbidities.

  • †Advanced diabetic complications include end-stage renal disease, amputation, and advanced retinopathy.

  • ‡Diminished life expectancy includes end-stage hepatic disease and cancer (excluding basal and squamous skin cancers).

  • §Other neurological conditions include gastroparesis, Parkinson disease, aphasia, dysphasia, hemiplegia, apraxia, epilepsy, and transient ischemic attack.

  • ‖Cardiovascular diseases include myocardial infarction, chronic heart failure, and ischemic vascular disease.

  • ¶OT, <7% (53 mmol/mol).

  • #NQF, <8% (64 mmol/mol).

  • **UT, >9% (75 mmol/mol).

  • ††OOR, <7% (53 mmol/mol) or >9% (75 mmol/mol).

  • ‡‡IR, 7.5–8.5% (58–69 mmol/mol).
