Multivariate analysis of mortality risk factors^a

Variable	B	SE	OR	95% CI	P
Hemodynamic compromise	3.19	0.82	24.50	4.9–121.2	<0.001
Inappropriate treatment	3.09	0.93	21.90	3.6–136	0.001
Mechanical ventilation	1.91	0.73	6.70	1.6–28.2	0.009
Constant	0.37	0.42			0.380

^aχ² = 50.91; degree of freedom = 3; P < 0.0001; goodness of fit = 86%. Correlation matrix did not demonstrate colinearity among variables. B, regression coefficients; SE, standard error; OR, odds ratio. Interactions between polymicrobial infections and each factor were taken into account.
