Figure 1

Mortality rates stratified by PALICC (OI) oxygenation categories at ARDS onset, and at 12 and 24 hours after. PALICC categories did not demonstrate any trend with mortality at ARDS onset, with subsequent timepoints showing a significant trend (see also Supplementary Figures 4 and 5 for all timepoints). Numbers above bars represent non-survivors and total number of patients in category. P values for a non-parametric test of trend, Hosmer-Lemeshow (HL) p values, and slopes and r2 of calibration curves are provided for each graph. Because of the low number of subjects (n = 6) in PALICC OI < 4 at ARDS onset, we removed this category for calibration tests.
