Predictive Value of 1-Hour Glucose Elevations during Oral Glucose Tolerance Testing for Cystic Fibrosis-Related Diabetes

Figure 2

Kaplan–Meier survival curves comparing baseline 1 hG and the likelihood of developing diabetes between (a) patients with elevated 1 hG (≥140 mg/dL) with normal glucose tolerance (2 hG < 140 mg/dL) to low 1 hG (<140 mg/dL) with normal glucose tolerance, (b) patients with elevated 1 hG (≥140 mg/dL) including those with impaired glucose tolerance (2 hG ≥ 140 mg/dL) to low 1 hG (<140 mg/dL) including those with impaired glucose tolerance, and (c) patients with elevated 2 hG (≥140 mg/dL) to low 2 hG (<140 mg/dL), regardless of 1 hG concentrations. 1 hG one-hour glucose and 2 hG two-hour glucose.
