Characterization of the cohort at baseline.

<p>a, the reverse association of CD4+ T-cell counts and viral loads in the study subjects at baseline. The X axis indicated CD4+ T-cell counts (cells/µl), and Y axis indicated viral loads; GraphPad Prism 5 was used to generate the trend line and r value. b and c, CD4+ T-cell counts and viral load among different groups at baseline. The X axis indicated different groups including HIV (HIV-1 mono infection), HIV/HCV (dual infection), and HIV/HCV/Tox (triple infection of HIV, HCV and toxoplasma). The Y axis indicated CD4+ T-cell counts (1b) and viral load (1c); d, the ratio of CD4+ T cells to viral loads among different groups, the ratios were calculated by dividing CD4+ T-cell counts by the value of viral loads in log10.
