Correlation between changes in cation levels and postreperfusion markers of hepatic viability and injury in the preclinical study

Reperfusion levels	Δ Potassium (mmol/L)		Δ Sodium (mmol/L)
	r s	P value	r s	P value
Cellular ATP	−0.85	<.001	0.58	.048
Peak ALT	0.81	<.001	−0.61	.02
Peak lactate	0.92	<.001	−0.72	.008

Both DHOPE and control livers were included in a bivariate analysis to correlate changes in potassium and sodium levels upon "ex situ reperfusion" (30 minutes after the start of NMP) with levels of cellular energy marker ATP and perfusate peak levels of ALT and lactate. Data are presented as Spearman's correlation coefficient (r _s).

ATP, adenosine triphosphate; ALT, alanine aminotransferase; NMP, normothermic machine perfusion.
