Probability of antiretroviral therapy initiation by baseline CD4⁺ cell count.

The probability of antiretroviral therapy initiation within 6 months of initiating HIV care was calculated as the number of individuals who initiated antiretroviral therapy within 6 months of the date of their earliest CD4⁺ cell count divided by the total number of individuals who had a first CD4⁺ cell count date. Probabilities were calculated by 10-cells/μl bins of earliest CD4⁺ cell counts (the first CD4⁺ cell count the individual had after initiating HIV care).
