Measure Description: The Phenotypic Sensitivity score (PSS) was defined as the total number of ARVs in optimized background therapy (OBT) to which the subject's viral isolate showed phenotypic sensitivity, based on pre-study resistance tests. The PSS score range is from 0 (meaning there was no ARV the subject was sensitive to) to >=3 (the subject was sensitive to >=3 of the ARVs in his/her OBT). If no resistance results were available for a drug, it was scored as one active drug in the PSS if there was history of prior use, and was considered not active if no prior use. Scoring did not include Raltegravir.

Measure Description: The Genotypic Sensitivity score (GSS) was defined as the total number of ARVs in OBT to which the subject's viral isolate showed genotypic sensitivity, based on pre-study resistance tests. The GSS score range is from 0 (meaning there was no ARV the subject was sensitive to) to >=3 (the subject was sensitive to >=3 of the ARVs in his/her OBT). If no resistance results were available for a drug, it was scored as one active drug in the GSS if there was history of prior use, and was considered not active if no prior use.
