Bivariable linear regression of plasma CXCL10 and the proportion of CD16⁺ monocytes.

<p>A comparison of the slopes between HIV negative (open circles, dashed line; n = 53) and HIV positive (closed circles, solid line; n = 23) groups and the relationship with age for (a) % CD16⁺ monocytes determined by whole-blood flow cytometry, (b) plasma CXCL10 and (c) sCD163 levels determined by ELISA.
