Lactobacillus level	Events	Univariate analysis			Multivariate analysis
		HR (95% CI)	P-value		HR (95% CI)	P-value
Multivariate Cox proportional hazard model adjusted for age, left ventricular ejection fraction, high-sensitivity C-reactive protein, TroponinT, low-density lipoprotein, and brain natriuretic peptide. HR: hazard ratio.
