Statistics: Generalized Linear Models (GLM) with a gamma distribution (log-link) (dependent variable: plasma metabolites; independent variable: HIV-infection), adjusted by epidemiological characteristics (age, gender and body mass index). P-values were adjusted by FDR correction for multiple comparisons (Benjamini and Hochberg). Statistically significant differences are shown in bold.

Abbreviations: RT, retention time; aAMR, adjusted ratio of the arithmetic means; CI, confidence interval; p-value, level of significance; q-value, adjusted p-value by FDR correction; GC-MS, gas chromatography–mass spectrometry; LC-MS ESI+, liquid chromatography–mass spectrometry, positive electrospray ionization; LC-MS ESI+, liquid chromatography–mass spectrometry, negative electrospray ionization; LysoPC, lysophosphocoline; LysoPE, lysophosphatidylethanolamine; HpOTrE, hydroperoxy-octadecatrienoic acid; DiHOTrE, dihydroperoxy-octadecatrienoic acid; EpODE, epoxy-octadecadienoic acid.
