97 participants were enrolled; 3 participants who did not meet the inclusion criteria for treatment duration were excluded.

Treatment Perception of QD (Once a Day) Dosed Kaletra (Tablets)

Participant treatment satisfaction was measured using the HIVTSQ, which consists of 10 items (1-Satisfaction, 2-HIV Control, 3-Adverse Effects, 4-Level of Demand, 5-Convenience, 6-Flexibility, 7-Knowledge, 8-Life Habits, 9-Recommendability, and 10-Willingness to Continue). Items are scored from 0 (very dissatisfied) to 6 (very satisfied), other than item 4, which has an inverted score from 6 (very demanding) to 0 (very undemanding). Each single item was considered for the evaluation of the primary outcome.

The HIVTSQ consists of 10 items (1-Satisfaction, 2-HIV Control, 3-Adverse Effects, 4-Level of Demand, 5-Convenience, 6-Flexibility, 7-Knowledge, 8-Life Habits, 9-Recommendability, and 10-Willingness to Continue). Items are scored from 0 (very dissatisfied) to 6 (very satisfied), other than item 4, which has an inverted score from 6 (very demanding) to 0 (very undemanding). The items are aggregated to 3 different dimensions: the Overall Satisfaction dimension, with a maximum score of 54 (items 1, 2, 3, 5, 6, 7, 8, 9 and 10); General/Clinical Satisfaction dimension, with a maximum score of 30 (items 1, 2, 3, 9 and 10); Lifestyle dimension, with a maximum score of 24 (items 5, 6, 7 and 8). Each dimension was considered for the evaluation of the primary outcome. For each participant, each dimension score was calculated as a sum of the individual item scores.

The HIVTSQ consists of 10 items (1-Satisfaction, 2-HIV Control, 3-Adverse Effects, 4-Level of Demand, 5-Convenience, 6-Flexibility, 7-Knowledge, 8-Life Habits, 9-Recommendability, and 10-Willingness to Continue). Items are scored from 0 (very dissatisfied) to 6 (very satisfied), other than item 4, which has an inverted score from 6 (very demanding) to 0 (very undemanding). The mean score per item was compared between cohorts.

The mean score per dimension was compared between cohorts.

Number of days without medication was assessed by 1 of the 6 items on the patient questionnaire Simplified Medication Adherence Questionnaire (SMAQ): How many full days have you missed your medication since your last visit? (Please see Outcome Measure 6 for details regarding the remaining 5 items on the SMAQ.)

Participants' adherence was classified according to answers for 5 of 6 items on the participant questionnaire Simplified Medication Adherence Questionnaire (SMAQ): 4 yes/no questions: Do you ever forget to take your medicines? Do you take your medicines at the instructed time? If you ever feel ill, do you stop taking the medication? Have you ever missed your medication during weekends?; plus the following: In the past week, how many times have you missed your medication? (0, 1-2, 3-5, 6-10, \>10). (Please see Outcome Measure 5 for details regarding the 6th item on the SMAQ.) Perfect adherence = no dose was forgotten, medication was not skipped for any reason, and the schedule was not modified; adequate adherence = no dose was forgotten, but at least one dose was not taken at the indicated time; poor adherence = one or more doses were not taken.

Participants' cumulative reasons for starting or switching to a LPV/r QD regimen were tabulated via the following yes/no questions entered on the case report form by the physician: simplification (simp) as reason to change to LPV/r QD; preference (pref) of patient as reason to change to LPV/r QD; adjustment to other antiretrovirals (adjust to ARV) as reason to change to LPV/r QD; adherence as reason to change to LPV/r QD; patient's lifestyle as reason to change to LPV/r QD; tolerability as reason to change to LPV/r QD.

The HIVTSQ consists of 10 items (1-Satisfaction, 2-HIV Control, 3-Adverse Effects, 4-Level of Demand, 5-Convenience, 6-Flexibility, 7-Knowledge, 8-Life Habits, 9-Recommendability, and 10-Willingness to Continue). Items are scored from 0 (very dissatisfied) to 6 (very satisfied), other than item 4, which has an inverted score from 6 (very demanding) to 0 (very undemanding). The items are aggregated to 3 different dimensions. The Overall Satisfaction dimension has a maximum score of 54 (items 1, 2, 3, 5, 6, 7, 8, 9 and 10). The mean of the individual item scores were dichotomized as 'mean score \<5 (lower participant perception of LPV/r QD)' and 'mean score ≥5 (high or very high participant perception of LPV/r QD).' The dependent variable of a mean score \<5 was correlated with the independent variables of viral load and time on treatment (see Outcome Measures 9 and 10), to determine the factors associated with a participant's lower perception of QD LPV/r treatment.

Viral load change was categorized as either 'detectable to undetectable,' 'undetectable to undetectable,' or 'current detectable' (includes participants whose viral load changed from undetectable to detectable and those whose viral load was detectable throughout). This independent variable was correlated with the percentage of participants with the dependent variable of a Human Immunodeficiency Virus Treatment Satisfaction Questionnaire (HIVTSQ) Overall Satisfaction dimension mean score value of \<5 (see Outcome Measure 8), to determine the factors associated with a participant's lower perception of QD LPV/r treatment (see statistical analyses for odds ratio).

Participants' perceptions of the QD and BID LPV/r regimens using data from the overall study population of QD-KAPITAL and from Cohort 2 of a 2007-2008 study, respectively (KAPITAL2, Casado et al. See Detailed Description for full reference). The KAPITAL2 cohort was comprised of HIV-infected participants treated with LPV/r BID from ≥3 months to \<2 years for at least 1 month before inclusion in the study. Data for the overall study population of QD-KAPITAL are provided here, but a comparison to Cohort 2 from the KAPITAL2 study is not presented.

Adherence to LPV/r QD therapy (overall study population of QD-KAPITAL) compared with that of LPV/r BID therapy using data of Cohort 2 from a 2007-2008 study, respectively (KAPITAL2, Casado et al. See Detailed Description for full reference). The KAPITAL2 cohort was comprised of HIV-infected participants treated with LPV/r BID from ≥3 months to \<2 years for at least 1 month before inclusion in the study. (A full comparison of the adherence between the QD-KAPITAL study and the KAPITAL2 study could not be made due to formal differences in the applied adherence questionnaires; therefore, the above in-common specified item was compared.) Data for the overall study population of QD-KAPITAL are provided here, but a comparison to Cohort 2 from the KAPITAL2 study is not presented.
