These patients (n = 32) were documented as “antiretroviral therapy (ART) eligible” in the program records and started on ART even though the CD4/World Health Organization (WHO) staging criteria were either not documented or did not match eligibility criteria. They were considered “ART eligible” for the purpose of this analysis.
