Observed and predicted 6-month mortality by deciles of arterial oxygen tension (PaO 2 ). PaO2 was divided by deciles. Predicted risk of death matched observed mortality very well within deciles with R L 2 values between 0.088 and 0.987. The predicted probability of death was calculated using the following variables: acute physiology and chronic health evaluation II (APACHE II) index independent on oxygenation (AP2no-ox), admission year (before or after 2007), emergency operation, intracranial pressure monitoring, controlled hypothermia and platelet count.
