Sex (female vs male)	1.48	(0.48, 4.65)	0.494
Diabetes	7.13	(2.03, 27.32)	0.003	6.29	(1.48, 31.34)	0.016
Hypertension	3.41	(1.08, 11.35)	0.039	1.63	(0.38, 6.87)	0.504
Heart diseases	4.21	(0.83, 23.79)	0.083	2.94	(0.42, 21.78)	0.271
Hepatic dysfunction	7.69	(2.27, 33.33)	0.002	5.88	(1.45, 33.33)	0.018

Only variables with P < 0.1 in univariate logistic regression were analyzed in multivariate analysis. OR: Odds ratio; 95%CI: Two tailed 95% confident interval.
