  • Data are presented as Pearson correlation coefficient, unless otherwise stated. Bold indicates statistical significance. sRaw: specific airway resistance; LCI: lung clearance index; Scond: conducting zone contribution to ventilation inhomogeneity; Sacin: acinar zone contribution to ventilation inhomogeneity. #: with both pathology and outcome data for that variable.
