Figure 2

Oxygenation index (OI) in survivors versus non-survivors and high frequency oscillatory ventilation (HFOV) versus conventional mechanical ventilation (CV). OIs are represented by diamonds as means with bars as 95% confidence intervals (CI). Reported p-values for baseline OI are corrected for study site, ventilatory index, APACHE II score, age and weight. The baseline OI did not significantly predict mortality in all patients or in HFOV (p = 0.06 and p = 0.41, respectively). §Baseline OI was significantly different between survivors and non-survivors in the CV group (p = 0.04). Significant differences between OI responses were calculated by linear mixed model analyses. #Significant difference in OI response between HFOV and CV (p = < 0.01). OI response did not differentiate between survivors and non-survivors in all patients or in CV and HFOV separately (p = 0.28, p = 0.12 and p = 0.95, respectively).
