TF expression is correlated with the magnitude of viremia and is weakly correlated with CD4⁺ T-cell counts. (A) Correlation between the proportion of TF⁺ monocytes and plasma levels of HIV RNA in patients (r = 0.57, P < .001). (B) Correlation between the proportion of TF⁺ monocytes and circulating CD4⁺ T-cell numbers in patients (r = −0.32, P = .014).
