Cognitive Intra-Individual Variability as an Outcome or Moderator of Speed of Processing Training in Aging Adults with HIV-Associated Neurocognitive Disorder: A Secondary Data Analysis of a 2-Year Longitudinal Randomized Clinical Trial.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Objective: Cognitive intra-individual variability (IIV), dispersion of cognitive performance across cognitive domains, indicates diminished cognitive control resulting from brain pathology or aging. For people with HIV-Associated Neurocognitive Disorder (HAND), cognitive IIV may interfere with and/or be improved by cognitive training. In this current secondary data analysis, we explored whether cognitive IIV functions as an outcome or moderator variable in speed of processing (SOP) training in middle-aged and older people living with HIV (PLWH). Method: In this randomized clinical trial, 216 PLWH with HAND or borderline HAND were randomized to either: 1) 10 hours of SOP training; 2) 20 hours of SOP training, or 3) 10 hours of Internet Navigation Control Training. Participants completed a seven-domain cognitive battery at baseline, posttest after training, and years 1 and 2 follow up; from this, the coefficient of variation ( Results: Using linear mixed-effect models, no strong pattern of SOP training effects were detected on cognitive IIV. However, a three-way interaction tests between time, group, and baseline cognitive IIV Conclusions: Although SOP training did not improve cognitive IIV, cognitive IIV may be a modifier of SOP training. Implications for future research and other types of training are provided.
