Plasma acylcarnitines and lysophophatidylcholine (LysoPC) species are different between breast-fed (BF, green) and formula-fed (Experimental formula, EF, orange; Standard Formula, SF, red) infants. (a) Principal component analysis (PCA) of generalized log transformed plasma acylcarnitines measured in the positive-ion mode of untargeted LC-MS. (b) Significantly different plasma acylcarnitine species were evaluated using Kruskal-Wallis with Dunn’s posthoc comparison. (c) PCA of generalized log transformed plasma LysoPC species measured in both the positive- and negative- ion mode of untargeted LC-MS. The significantly different plasma LysoPC species in (d) the positive- ion mode and (e) the negative- ion mode were evaluated using Kruskal-Wallis posthoc Dunn’s test.
