The median cell surface expression and 95% confidence intervals are shown for CD64 (A), CD163 (B) and CD143 (C) on monocyte subsets in HIV and control subjects.

<p>Expression on classical monocytes is significantly different between HIV and control groups for CD64 (p<0.001) but not for CD163 or CD143. Expression of all cell surface markers on CD16⁺ monocytes, however, are significantly different between the HIV infected and control groups (* p<0.05, ** p<0.01 *** p<0.001).
