Notes:

• Regional and country level aggregate data are generated from regional patient-level databases, using the IeDEA Data Exchange Standard (DES). Data reflects the situation at clinics contributing data to IeDEA, which may not be nationally representative.
• All ART-naïve patients newly enrolling in HIV care from 2010 to present at a site participating in IeDEA were eligible for inclusion if they had at least 15 months between enrollment and database close or transfer to another site of care. The following patients were excluded: patients with incomplete data related to age, sex, and site of enrollment and patients with evidence of ART initiation prior to the date of enrollment.

Definitions:

• Enrollment in HIV care: Enrollment in HIV care at a site participating in the IeDEA consortium, based on the date of enrollment recorded in the database
• Enrollment CD4 count: CD4 count measure within 3 months (+/-) of the date of enrollment, or no more than 30 days after ART initiation among those initiating treatment within 3 months of care entry. For patients with >1 CD4 count, CD4 measure closest to enrollment date is used.
• Median CD4 count at enrollment: Median CD4 count among patients with a recorded CD4 count measure within 3 months of enrollment and no more than 30 days after ART initiation. For patients with >1 CD4 count within the ascertainment window, CD4 measure closest to enrollment date is used.
