Data are presented as n, n (%) or median (interquartile range), unless otherwise stated. Infection was defined as a decline in forced expiratory volume in 1 s, symptoms and positive infectious parameters. BOS: bronchiolitis obliterans syndrome. #: occurring in the first year; ¶: after P. aeruginosa colonisation was proven once, eradication.
