Concentrations of total and oxidized forms of IgM and IgG in HIV- controls and the different HIV + groups. Figure shows HIV-negative controls (HIV-), untreated HIV + subjects with CD4 < 250 (< 250) or > 500 (> 500), and HIV + treated subjects on a boosted protease inhibitor regimen (PI/r) or an NNRTI regimen (NNRTI). A. MDA-LDL IgG, B. OxLDL IgG, C. Ratio MDA-LDL IgG/total IgG, D. Ratio OxLDL IgG/total IgG, E. Total IgG, F. MDA-LDL IgM, G. OxLDL IgM, H. Ratio MDA-LDL IgM/total IgM, I. Ratio OxLDL IgM/total IgM, J. Total IgM. Boxes encompass interquartile ranges with median (line), whiskers designate the range. *p < 0.05, **p < 0.01, ***p < 0.001, a.u.: arbitrary units.
