Figure 1From: Role of C-reactive protein as a biomarker for prediction of the severity of pulmonary exacerbations in patients with cystic fibrosis FEV 1 (% predicted) before and after exacerbations. The boxes represent the middle 50% of patients; the whiskers include all patients in each group. The horizontal line within the box represents the median FEV1. The x axis represents the best FEV1 in the 12 months before admission (baseline); FEV1 at hospitalization (initial); and the best FEV1 at the end of antibiotic therapy (final).Back to article page
