Relationship between MetS and Different In-hospital Outcomes Using Multivariable Logistic Regression

Criteria	Heart Failure			Mortality
	OR	95% CI	P	OR	95% CI	P
Age	1.04	1.03-1.06	<0.001	1.07	1.02-1.13	0.004
Gender (Male)	0.48	0.30-0.79	0.004	0.18	0.047-0.72	0.016
Low HDL-C*				Infinite	N/A	0.027
Hypertension				0.11	0.03-0.42	0.001
High blood sugar	1.71	1.16-2.53	0.006	6.49	1.13-37	0.035

OR = odds ratio; CI = confidence interval; HDL-C = high-density lipoprotein cholesterol; N/A = not applicable.

The variables that were dropped out of the multivariable logistic regression using the stepwise-backward elimination method included smoking, hypertriglyceridemia and abdominal obesity.

^*In the case of in-hospital mortality, the odds ratio for low HDL-C was infinite, due to one of the cells being zero [38].
