Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
These three groups of participants with HIV-1 infection were at first registered as three different studies: KAL1RO (this study, NCT01083810, n=137), KAL2RO /KAL5RO (NCT01083836, n=92), and KAL6RO (NCT01081470, n=55) but were now reconciled under KAL1RO (NCT01083810) as a single study with three reporting groups.
