Current glucose metabolism status was determined by most recent OGTT when available (8 subjects) or by alternative guideline-recommended criteria for CFRD: most recent A1C of >6.5% or RPG >200 mg/dL with symptoms. For CGM, the following criteria were used for interpretation: fasting glucose >126 mg/dL or random glucose >200 mg/dL indicated CFRD; random glucose >140 mg/dL indicated IGT; fasting glucose >100 mg/dL indicated IFG.
