Figure 2. Relationship of viral tropism of ARV-naive and ARV-failing patients.

Figure 2

A) Frequency of X4/dual/mixed- and R5-utilizing viruses in patients failing treatment and treatment-naive individuals. Bar graph indicating results from the trofile assay comparing the proportion of patients with R5 viruses to those harbouring X4/dual/mixed viruses in HAART-naive versus HAART-failing patients (p=0.02, Fisher’s exact test). B) CD4 counts and coreceptor usage in HAART-naive patients and HAART-failing patients. Dot graph indicating results from trofile assay. ARV-naive patients with X4/D/M viruses had a lower CD4 count than ARV-naive patients with R5 viruses (p=0.014, unpaired t test). ARV-failing patients with X4/D/M viruses had a lower CD4 count than ARV-failing patients with R5 viruses (p=0.02, unpaired t test). For ARV-failing patients nadir CD4 counts are respresented C) Association of TAMs in X4/D/ M viruses. Bar graph indicates trofile assay results. D/M indicates dual/mixed viruses.
