Odds ratios of the different etiologies with respect to the complications of upper gastrointestinal bleeding

Complication	HBV cirrhosis	HCV cirrhosis	Alcoholic cirrhosis	Autoimmune cirrhosis	Mixed etiology	Cryptogenic cirrhosis	Others
	(n = 6239)	(n = 226)	(n = 459)	(n = 163)	(n = 400)	(n = 237)	(n = 356)
UGIB (Y/N)	739/5500	24/202	98/361	16/147	47/353	41/196	41/315
OR	1.00	1.07	1.89	0.90	0.83	1.76	1.01
95%CI		0.68-1.69	1.48-2.41	0.50-1.60	0.60-1.16	1.21-2.52	0.72-1.44
P value		0.759	< 0.001	0.713	0.282	0.002	0.938

Others: cases excluding the six previous etiologies; OR (95%CI) was calculated with a multivariate logistic model adjusted for age, gender, year, birthplace (Cantonese, Other Chinese, Foreigner), and Child-Pugh value using the stepwise forward method, and the P values were determined by unconditioned logistic regression. HBV: Hepatitis B virus; HCV: Hepatitis C virus; UGIB: Upper gastrointestinal bleeding.
