TABLE 4.

Baseline plasma selenium biomarkers and methionine concentration in Child-Pugh classes¹

	Child-Pugh class A (n = 27)	Child-Pugh class B (n = 30)	Child-Pugh class C (n = 25)	P
SEPP1, mg/L	5.6 ± 1.6^x	4.0 ± 0.9^y	3.3 ± 0.8^y	<0.001
GPX, U/L	123 ± 26	124 ± 30	148 ± 46	0.062
Selenium, μg/L	107 ± 18^x	88 ± 13^y	82 ± 12^y	<0.001
Methionine, μmol/L	29 ± 10^x	36 ± 14^y	58 ± 76^z	<0.001

All values are means ± 1 SDs. P values were based on the Kruskal-Wallis H test. Values that do not share a common superscript letter are significantly different at P < 0.05. GPX, glutathione peroxidase; SEPP1, selenoprotein P.
