  1. The quantitative data are shown as median data and inter quartile range data in brackets
  2. The occurrence data are shown as no. (%). Values indicate no. of positive results/total no. of patients with available assay results
  3. Kruskal-Wallis test for continuous variables or Fisher’s exact test for categorical variables was used for comparison between groups when applicable with p < 0.05 as significant
  4. Abbreviations: BMI, body mass index; ICU, intensive care unit; HFNC, high flow nasal catheter oxygen therapy; PFTs, pulmonary function tests; FVC, forced vital capacity; FEV1, forced expiratory volume in the first 1 s of expiration; PEF, peak expiratory flow; DLCO, diffusing capacity of the lung for carbon monoxide; TLC, total lung capacity; RV, residual volume
  5. #Pulmonary function tests were expressed as percent of the predicted value
