Decline of pulmonary function according to the colonization of Haemophilus influenzae in bronchiectasis patients. The annual decline of (a) FEV1 (p = 0.382) and (b) FVC (p = 0.628) did not show significant differences regardless of Haemophilus influenzae colonization in bronchiectasis patients. Solid lines indicate patients with Haemophilus influenzae colonization, while dashed lines indicate patients without colonization. Abbreviations: FEV1, forced expiratory volume in one second; FVC, forced vital capacity; CI, confidence interval
