Data are means ± SD unless otherwise indicated. Change in weight and lung function in the preceding 12 months in 31 patients with cystic fibrosis, excluding the 2 patients with BG_{120 min} ≥11.1 mmol/l (diabetic by WHO criteria) are shown. Groups are compared according to three different glycemic cutoffs.
