From: High frequency oscillatory ventilation compared with conventional mechanical ventilation in adult respiratory distress syndrome: a randomized controlled trial [ISRCTN24242669]

Figure 3

Post hoc analysis of the treatment effect on mortality relative to baseline oxygenation index (OI). On the y-axis the odds ratio of mortality (OR) adjusted for study site, OI, ventilatory index, APACHE II score, age and weight is presented by diamonds and 95% confidence intervals by bars. On the x-axis the different analyses are depicted including patients with increasing levels of initial OI at study entry. N denotes the number of patients in each subgroup. CI, confidence interval; CMV, conventional mechanical ventilation; HFOV, high frequency oscillatory ventilation.
