Fig. 3From: Pulmonary exacerbations and clinical outcomes in a longitudinal cohort of infants and preschool children with cystic fibrosisRelationship between lung function at 7 years and number of exacerbations: A loess curve for FEV1 (blue line) and FVC (red line) was used to display the association and is plotted with a 95% confidence interval (shaded bands). Higher FVC was associated with increased exacerbation frequency whereas no association was seen between FEV1 and exacerbation frequencyBack to article page
