Fig. 4From: Treatment intensity, age and outcome in medical ICU patients: results of a French administrative databaseRelationship between the standardized mortality ratio (SMR = observed mortality/expected mortality) and age in the four groups of treatment intensity. SMR increased with age in the lower intensity groups, reflecting either inadequate treatment intensity or a lower efficiency of treatment for the older patients. SMR was not related to age in the highest intensity group, reflecting a similar efficiency of such treatment whatever was the age of the patientsBack to article page
