Nasal Nitric Oxide Levels in HIV Infection: A Cross-Sectional Study

Figure 1

Nasal NO levels across the 3 groups of participants. Mean nasal NO levels in HIV-infected individuals with suppressed viral load on ART (black bar), HIV-infected individuals with detectable viral loads (VLs) off antiretroviral therapy (ART) (grey bar), and healthy controls (HC, white bar). The differences of mean nasal NO levels among groups did not reach statistical significance.
