Non-invasive model for predicting esophageal varices based on liver and spleen volume

Table 2 Comparison of general characteristics of the external validation group, n

Parameter	Patients with EVs, n = 37	Patients without EVs, n = 19	All patients, n = 56	P value
Age, yr	51.46 ± 10.87	53.03 ± 11.41	54.68 ± 10.93	0.39
Male (%)	20 (54.1)	10 (52.6)	30 (53.6)	0.43
Etiology, HBV/HCV	27/10	15/4	42/14	0.56
Child-Pugh class, A/B/C	13/21/3	12/7/0	25/28/3	< 0.05
Red sign	14	0	14	< 0.01

P < 0.05 is considered statisticall significance. EVs: Esophageal varices; HBV: Hepatitis B virus; HCV: Hepatitis C virus.
