    Time frame: At Week 1 and Week 9

    The PIN questionnaire is characterized by the dimension scores based on 4 domains including Bother from injection site reactions (ISRs), Acceptability, Leg movement and Sleep categories. The objective of this endpoint is to present analysis of 2 (out of 4) PIN domains: Bother from ISRs and Acceptability. This questionnaire contains 21 items that measure pain at injection site, local site reactions, impact on functioning and willingness to pursue injectable treatment outside of a clinical trial. Domain scores were calculated as a mean of all items with the domain. Scores range from 1 to 5,and questions are phrased in such a way as to ensure that 1 always equated with the most favorable perception of vaccination, and 5 the most unfavorable. Higher scores represent worse perception of injection. The objective of this outcome measure was to present the data separately for each treatment received (CAB, RPV).

  36. PIN Questionnaire in Domain Scores and Individual Item Scores - Return to IM Gluteal Injection Phase

  37. Change From Baseline to the PIN Questionnaire in Domain Scores and Individual Item Scores at Indicated Time Points - SC Injection Phase

    Time frame: Change from Baseline (Week -3) at Week 1 and Week 9

  39. Number of Participants With Their Treatment Preference Assessed Using Preference Questionnaire on Week 9 - SC Injection Phase

    Time frame: Up to Week 9

    A preference questionnaire was used to assess participant's preference for the subcutaneous injections compared with the gluteal injections. The "Preference" questionnaire included a single item question evaluating preference of HIV treatment. Participants were required to provide their response to Question, which stated "Which injection site do you prefer". The responses included Intramuscular Injections in the buttock, Subcutaneous Injections in the Abdomen and No preference.

  40. Number of Participants With Their Treatment Preference Assessed Using Preference Questionnaire on Week 17 - Return to IM Gluteal Injection Phase

    Time frame: Up to Week 17
