CF-related comorbidity data was unavailable for 8 cases (5 transient cases and 3 persistent cases). Data are presented as either median (interquartile range) or N (%). Either Wilcoxon rank-sum test or Fisher-exact probability at two-tailed were performed (p > 0.05).
ppFEV1, percent predicted forced expiratory volume in 1 second; ppFVC, percent predicted forced vital capacity; BMI, Body mass index.
*Denotes an n of 13 due to unavailability of clinical data for 1 case.
**Denotes an n of 8 due to unavailability of clinical data for 3 cases.
