Cognitive performance is measured by NPZ-8. The NPZ-8 is defined as the average of age and education adjusted z-scores of eight neuropsychological tests subcomponents in the neuropsychological test battery:

  1. Grooved Pegboard Dominant Hand (GPD)
  2. Grooved Pegboard Non-dominant hand (GPN)
  3. Choice Reaction Time (CRT)
  4. Sequential Reaction Time (QRT)
  5. Timed Gait (TIG)
  6. Trail Making Part A (TMA)
  7. Trail Making Part B (TMB)
  8. Symbol Digit (SYD)

[Units: Z-score]
Mean (Standard Deviation)
 -0.86  (0.72)   -1.08  (0.90)   -0.97  (0.82) 
[1] GDS is defined as the average of age and education adjusted z-scores of 14 individual deficit scores in the test battery, including Time Gait, Grooved Pegboard Test for the dominant and non-dominant hands, Trail Making Test parts A and B, Symbol Digit Test, simple and sequential reaction time - CalCAP, Hopkins Verbal Learning Test (Revised)- Learning, Delayed Recall and Recognition trials, and Stroop Color Interference Test-color, word, and interference tasks.
Cognitive Gross Motor Function Domain Z-Score [1] 
[Units: Z-score]
Mean (Standard Deviation)
 -2.44  (3.10)   -3.66  (4.16)   -3.06  (3.71)

[Units: Z-score]
Mean (Standard Deviation)
 -0.35  (0.96)   -0.73  (0.99)   -0.55  (0.99) 
[1] This is an average z-scores of Grooved Pegboard Dominant and Non-Dominant Hand Tests adjusted for age, sex, education, and African-American ethnicity. The grooved pegboard is a manipulative dexterity test requiring rapid visual-motor coordination. The test is completed using the dominant hand (GPD) and then using the non-dominant hand (GPN). The score for each hand is the time in seconds that the participant takes to complete the entire board.
Psychomotor Function Domain Z-Score [1] 
[Units: Z-score]
Mean (Standard Deviation)
 0.15  (1.00)   0.04  (1.03)   0.10  (1.01) 
[1] This is an average of z-scores of Trail Making Part A (TMA) and Trail Making Part B (TMB) tests adjusted for age, sex, education, and African-American ethnicity. The TMA and TMB tests are measures of planning ability, visual-motor speed and concentration. Subjects are required to connect randomly placed numbers in sequence (1-25 for TMA) or to sequentially connect both numbers and letters while alternating back and forth (1-A-2-B-3-C-4-D etc. for TMB). Scores are the time in seconds required to complete the tasks.
Fine Motor/Nonverbal Function Domain Z-Score [1] 
[Units: Z-score]
Mean (Standard Deviation)
 -1.11  (1.15)   -1.24  (1.18)   -1.18  (1.16) 
[1] This score is a age and education adjusted z score of Symbol Digit Test (SYD). This test assesses the participant's ability to maintain rapid visual-motor sequencing in a timed test. The score is the total number of correctly transcribed numbers in the time limit (90 seconds). Participants receive 1 point for each item filled in correctly.
Information Processing Function Domain Z-Score [1] 
[Units: Z-score]
Mean (Standard Deviation)
 -1.05  (1.52)   -1.03  (1.49)   -1.04  (1.50)

[Units: Z-score]
Mean (Standard Deviation)
 -1.33  (1.16)   -1.41  (1.12)   -1.37  (1.14) 
[1] This is the average of z-scores of Hopkins Verbal Learning Test- Revised, Learning and Delayed Recall Tests adjusted for age and education. The recognition test list comprises 24 words, consisting of 12 words from the original list and 12 "distracters". The subject must answer "yes" if the word was from the list and "no" otherwise. Twenty minutes after the third list from verbal learning and immediate recall, delayed recall is assessed by asking the subject to recall as many words as possible from the list. The score is the number of words that are correctly recalled from the original list.
Frontal Systems Function Domain Z-Score [1] 
[Units: Z-score]
Mean (Standard Deviation)
 -0.79  (0.98)   -1.05  (1.57)   -0.92  (1.32) 
[1] This is the average age and education adjusted z-scores of Stroop Color Interference Test (CTP) and interference task (STP). The Stroop Task is a measure of divided attentional abilities. Performance is measured by the amount of time required to read each of three cards: (1) blocks of colors, (2) names of colors, and (3) colored words. For each task, the time (in seconds) is the score that should be recorded on the form. A task that cannot be completed in 240 seconds is scored as incomplete.

Plasma RNA VL < 30 copies/mL   42   41   83 
missing   3   8   11

CSF RNA VL >=30 copies/mL   1   2   3 
CSF RNA VL <30 copies/mL   20   18   38 
missing   31   35   66

Central Nervous System (CNS) Penetration Score [1] 
[Units: Scores on a scale]
Mean (Standard Deviation)
 7  (3)   7  (3)   7  (3) 
[1] The baseline CNS penetration score is calculated based on the revised CNS penetration-effectiveness ranks (provided by Dr. Scott Letendre). The score is simply a sum of the ranks of all drugs which participants took at baseline. The better the drug penetrates, the higher the score. The range of ranks are 1 to 4, so the CNS penetration score is integer numbers greater than 1.
Stratification Variable 1 - CSF Viral Load (VL) - Pre-baseline [1] 
[Units: Participants]
     
CSF RNA VL < 30 copies/mL   21   22   43 
CSF RNA VL >= 30 copies/mL   3   4   7 
No Lumbar Punctures (LPs)   28   29   57 
[1] Participants were stratified based on two factors. One is CSF HIV-1 RNA. This variable has three levels using the TaqMan assay in CSF: (1) HIV CSF RNA VLs ≥30 copies/mL (detectable), <30 copies/mL (Undetectable), or no lumbar punctures (LPs). The assessment was conducted BEFORE the baseline in order to use this information for randomization.
Stratification Variable 2 - Objective or subjective Neuropsychological test - Pre-baseline [1] 
[Units: Participants]
     
Objective Neuropsychological (NP) Test   5   7   12 
Subjective NP Test   47   48   95 
[1] The 2nd stratification factor is progressive neurocognitive decline defined by objective or subjective criteria at pre-baseline. A decline of at least 1.0 standard deviation below age-matched and education-matched controls on two or more independent tests or 2.0 standard deviations below age-matched and education-matched controls on one test within 1 year before entry is defined as objective decline. Otherwise, subjective neurocognitive decline is defined by the participant or family member or caregiver AND a Center for Epidemiological Studies Depression score <16 within 45 days before entry.
Instrumental Activities of Daily Living (IADL) Summary Score [1] 
[Units: Scores on a scale]
Mean (Standard Deviation)
 0.12  (0.15)   0.13  (0.16)   0.12  (0.15) 
[1] The IADL questionnaire has 16 common tasks: 1. Housekeeping; 2.Managing Finances; 3. Buying Groceries; 4.Cooking; 5. Planning Social Activities; 6.Understanding Reading Materials/TV; 7.Transportation; 8.Using the Telephone; 9.Home Repairs; 10.Bathing; 11.Dressing; 12.Shopping; 13.Laundry; 14.Taking/Keeping Track of Medication; 15.Child Care; 16.Work. For each task, if the score at the time of evaluation is worse than the best in the past, an indicator of 1 is given; otherwise 0. The IADL score is a sum of 16 indicators divided by 16. The lower score indicates better. The range is from 0 to 1.
Medication Management Test (MMT) Score [1] 
[Units: Scores on a scale]
Mean (Standard Deviation)
 14.72  (1.41)   14.09  (2.52)   14.39  (2.08)

[Units: Z-score]
Mean (Standard Deviation)
 -0.54  (0.82)   -0.63  (0.92)   -0.58  (0.87) 
[1] This is the average of z scores of Trail Making Part A and Symbol Digit Tests. Trail Making Part A z score was adjusted for age, sex, education, and African-Ametrican ethnicity. Symbol Digit z score was adjusted for age and education.
