CFTR: cystic fibrosis transmembrane conductance regulator; BMI: body mass index; FEV1 % pred: per cent predicted forced expiratory volume in 1 s; ABPA: allergic bronchopulmonary aspergillosis; GI: gastrointestinal; Iva: ivacaftor; Lum: lumacaftor; Tez: tezacaftor; Elexa: elexacaftor; MRSA: methicillin-resistant Staphylococcus aureus. #: 10 recipients of other solid organ transplants were included in this group (7 liver, 2 kidney, 1 unspecified). ¶: percentages are computed excluding missing data. +: BMI z-score was only calculated for patients aged 2 years and over, using Centers for Disease Control and Prevention reference values [40]. §: FEV1 % pred was only calculated for patients aged 6 years and over.
