- p value: Mann–Whitney U test. Numeric computed tomography data. Percentages do not add to 100, because honeycomb and emphysema pattern fractions are not presented because of their clinical irrelevance in this cohort. Recruitment was associated with a decreased fraction of lung tissue with reticular pattern
- GGO ground glass opacity, IQR interquartile range, RI recruitment to inflation ratio
