Differences in AUCs of the individual comorbidity indices

Score	90-day mortality		1-year mortality
	AUC (95% CI)	p value	AUC (95% CI)	p value
CCI - ECI	-0.015 (-0.053 to 0.024)	0.46	0.014 (-0.012 to 0.04)	0.30
ECI - ASA	0.053 (0.001 to 0.105)	0.04	0.07 (0.032 to 0.109)	< 0.001
CCI - ASA	0.038 (-0.016 to 0.093)	0.17	0.084 (0.045 to 0.123)	< 0.001

AUC = area under the curve; ASA = American Society of Anesthesiologists; ECI = Elixhauser comorbidity index; CCI = Charlson comorbidity index.
