  • Data are mean ± SD, percent, and DR. Validity is based on reliability, reproducibility, and repeatability measures.

  • *The baseline glucose tolerance category is based on standard oral glucose tolerance testing 2-h glucose concentrations: NGT <7.8, IGT 7.8–11, and CFRD >11.1 (8). Normal healthy control subject data shown to be significantly different from all children and adolescents with CF;

  • P < 0.001.
