Is Frequent CD4 + T-Lymphocyte Count Monitoring Necessary for Persons With Counts ≥300 Cells/µL and HIV-1 Suppression?: Figure 1.

Among patients infected with human immunodeficiency virus (HIV), those with HIV-1 RNA <200 copies/mL and CD4 counts ≥300 cells/µL had a 97.1% probability of maintaining durable CD4 ≥200 cells/µL for 4 years. When non-HIV causes of CD4 lymphopenia were excluded, the probability rose to 99.2%. Our data support less frequent CD4 monitoring during viral suppression.
