Identification of metabolites that were significantly differentiating plasma profiles of AAA patients from controls.

A vs C - (+)/(−) means increased/decreased abundance in large aneurysm group in comparison to controls, S vs C - (+)/(−) means increased/decreased abundance in small aneurysm group in comparison to controls, A vs S - (+)/(−) means increased/decreased abundance in large aneurysm group in comparison to small aneurysm group. Identity of metabolites marked with asterix (*) was confirmed by analyzis of the standard.
