Reporting Groups
  Description
ARV naïve at Baseline ARV naïve participants had no previous experience with ARV. Participants received ARV combination treatment including raltegravir. Treatment of participants was at the discretion of the investigator who provided standard care in a real life setting.
Suppressed at Baseline Suppressed participants had previous ARV experience and had a viral load <50 RNA copies/mL at Baseline. Participants received ARV combination treatment including raltegravir. Treatment of participants was at the discretion of the investigator who provided standard care in a real life setting. One participant in this subgroup was excluded from analysis because of protocol violation (inclusion criterion not met).
Virological Failure at Baseline Virological failure participants had previous ARV experience and had a viral load >50 RNA copies/mL at Baseline. Participants received ARV combination treatment including raltegravir. Treatment of participants was at the discretion of the investigator who provided standard care in a real life setting. One participant in this subgroup was excluded from analysis because of protocol violation (inclusion criterion not met).
