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.
The median age and baseline CD4+ T-cell count of the study participants were 48 years (IQR 42–53) and 450 cells/mm3 (IQR 289–585).

Reporting Groups
Men on Raltegravir Measuring semen samples: Measure semen sample concentrations, obtain semen to plasma ratios across the dosing interval, the area under the concentration time curve of raltegravir in semen, the variability in penetration of raltegravir into the seminal compartment over the dosing period.
