The relationship between DAO level and clinical parameters in HBV-related decompensated cirrhosis. a, The plasma DAO level of readmission group with 6 month was higher than non-readmission group (P < 0.001). b, The plasma DAO level of SBP group was higher than non-SBP group (P < 0.001). c, The plasma DAO level of GI bleeding group was higher than non-GI bleeding group (P < 0.05). d, The plasma DAO level of HE group was higher than non-HE group (P < 0.01). e, There was no significant difference in DAO level between ascites group and non-ascites group (p > 0.05). f, There was no significant difference in DAO level between HBeAg possitive group and negative group (p > 0.05). g, There was no significant difference in DAO level between HbeAg possitive group and negative group (p > 0.05). h, There was no significant associations between DAO and ALT (p > 0.05). i, The DAO level was positively correlated with AST (r = 0.268, p = 0.002). j, The DAO level was positively correlated with TBIL (r = 0.493, p = 0.000). k, The DAO level was negatively correlated with ALB (r = − 0.305, p = 0.000). l, The DAO level was negatively correlated with PTA (r = − 0.233, p = 0.007)
