However, 119 metabolites including choline, tryptophan betaine, indole, ornithine, three acylcarnitines, four cholesteryl esters, two lysophosphatidylcholines, five long-chain diglycerides, and 101 unsaturated (very) long-chain triglycerides were nominally significant with P < 0.05, suggesting potential links between these metabolites and early revision.
