Divergence in the results of risk-adjusted inter-hospital mortality comparisons from the observed data set

		MI	Listwise deletion	Omission of physiological variables
% difference in OR	Median*	3.6	18.8	60.5
	(Q1;Q3)	(2.4;6.1)	(8.2;41)	(27;138)
% difference in SE	Median†	−0.08	−66.6	20.6
	(Q1;Q3)	(−0.6;0.6)	(-82;-57)	(12;28)

OR, Odds Ratio; SE, Standard Error; Q1;Q3; Inter-quartile range, MI, Multiple Imputation

^*For MI = MEDIAN|(( observed OR − MI OR)/observed OR) × 100) |

^†For MI = MEDIAN (((observed SE − MI SE)/observed SE) × 100)
