ICU survival at 28 days according to the application of protective ventilation. Solid red line represents survival of patients who received protective ventilation on day 1, defined as tidal volume of less than or equal to 8 mL/kg of ideal body weight and plateau pressure less than or equal to 30 cmH2O; solid blue line represents the survival of patients who were ventilated with non-protective ventilation; the shaded area represents the 95% confidence intervals. The p value was obtained with a Cox proportional hazards model, adjusted for PF ratio, respiratory system compliance, pH, and PEEP
