  Hide Outcome Measure 3

Measure Type Primary
Measure Title Changes in CD4 Count
Measure Description Increases in CD4 count are a biomarker for antiretroviral treatment effectiveness in restoring immunologic function. Changes in participants' CD4-positive (CD4+) T-lymphocyte counts were assessed by measuring the change from Baseline in the number of CD4+ cells at scheduled study visits.
Time Frame Baseline to 3 months  
Safety Issue No  

Population Description
Explanation of how the number of participants for analysis was determined. Includes whether analysis was per protocol, intention to treat, or another method. Also provides relevant details such as imputation technique, as appropriate.
Change from baseline analysis is based on participants with CD4 count results available at 3 months.
