Values presented as mean (95%CI) and P-values obtained from analysis of covariance. The natural logarithm of each biomarker was modeled as the outcome variable with disease group and MELD as the independent variables. A superscript of a indicates
a
P < 0.05,
b
P < 0.01. ADMA: Asymmetric dimethylarginine; SDMA: Symmetric dimethylarginine; MMA: Monomethylarginine; TMAO: Trimethylamine N-oxide.
