a Kaplan-Meier analysis of survival effect in cystic fibrosis patients with FEV1 < 30%. Median survival was 37 (CI = 16.4–57.6) months and mean survival was 50.5 (CI = 39.3–61.6) months. b Kaplan-Meier survival functions comparing body mass index (BMI) < 18.5 kg/m2 and BMI ≥ 18.5 kg/m2 in patients with cystic with FEV1 < 30%. Mean survival in patients with BMI < 18.5 kg/m2 = 39.9 (CI 25.8–54.0) months (median survival = 36 monhs, CI = 18.7–53.3) and in patients with BMI ≥ 18.5 kg/m2 median survival = 65.5 (CI 49.2–81.8) months (median survival not measurable), Log-rank test P = 0.028
