Table 2 Preoperative and intraoperative recipient variables, stratified by severity of hepatic ischemia reperfusion injury (hIRI) as defined by: no hIRI: AST <200; mild hIRI: AST <2000, moderate hIRI: 2000 <AST <5000, severe hIRI: AST >5000. Values are reported as means and standard deviations unless otherwise specified. P values represent significance of pairwise comparison in relation to no hIRI group.
