  1. Values are median (inter-quartile range), unless otherwise noted.
  2. AP-values are from the Mann-Whitney U test for comparing medians, except for sex which uses a Chi-square test on the percentage of male/female.
  3. BAL, Bronchoalveolar lavage; ICU, Intensive Care Unit; PF Ratio, PO2: FiO2 ratio.
  4. ARDS day: the day BALF was obtained relative to ARDS onset as defined by mechanical ventilation initiation.
