Notes: Estimated coefficients and associated statistics for the best submodel chosen by backwards elimination with the AIC. The coefficient “risk = sepsis” gives the difference in the log odds of the outcome for the sepsis group, as compared to the trauma group, with a positive coefficient indicating that the outcome is more likely within the sepsis group, other variables being equal. The P-values are for two-sided tests.
