Characteristics and pulmonary function tests in the year following the first detection of MDR bacteria in MDR group and in control group.

	Patients Colonized with MDR Bacteria (n = 7)	Matched Controls (n = 14)
Age (years)	12.1 ± 1.4	11.9 ± 4.0
BMI (kg/m2)	16.3 ± 2.5	18.6 ± 2.3 **
FEV1 pp %	85.4 ± 14.6	88 ± 13.2
FVC pp %	95.0 ± 13.4	90.3 ± 11.3
FEV1/FVC %	77.7 ± 10.0	95.8 ± 7.8 **
Pex	3.5 ± 3.2	1 ± 1.5 *

Data are expressed as mean ± SD. BMI, body mass index; FEV₁, forced expiratory flow in 1 s; FVC, forced vital capacity; pp, percent of predicted; Pex, pulmonary exacerbations. * t = 2.06, p < 0.05; ** t = 3.58, p < 0.002.
