P/F ratio versus bronchoalveolar lavage fluid (BALF) protein. The relationship between P/F ratio and BALF protein content was evaluated in [A] all subjects (n = 21), [B] non-ARDS subjects (n = 14) and [C] ARDS subjects (n = 7). Significant negative correlation between P/F ratio and BALF protein was observed in all subjects and ARDS subjects.
