Means of titers of TTV in the saliva and HIV in the circulation in relation to the CD4+ lymphocytes count from all subjects being treated with antiretroviral therapy. The TTV and HIV titers were proportionately increased when CD4+ count was decreased. The vertical bar indicates the Standard Deviation value of the titer of TTV and HIV in log10 copies/ml. ****p < 0.0001; ***p < 0.0005; ns, statistically not significant.
