Figure 2. 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.

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).
