Longitudinal Changes in Cognition and Brain Imaging in Persons With Human Immunodeficiency Virus.
Article in The Journal of infectious diseases, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundAs persons with human immunodeficiency virus (PWH) live longer, interactions between human immunodeficiency virus (HIV), aging, and structural brain integrity become increasingly vital for understanding cognitive disorders. This study analyzed the effects of aging, HIV serostatus, and viral load on cognition and brain volumes in a large cohort of persons without HIV (PWOH), PWH with undetectable virus (PWHU) (HIV RNA ≤50 copies/mL), and PWH with detectable virus (PHWD) (HIV RNA >50 copies/mL). Cross-sectional and longitudinal data were included.
methodsCognitive composites (NPZ4) and brain volumes were obtained from 259 PWOH, 264 PWHU, and 84 PWHD with a total of 841 sessions. A series of generalized additive mixed models explored group differences in the relationship between age and cognition, age and regional brain volumes, and interactions between age and brain volumes on cognition.
resultsPWOH and PWHU exhibited similar change in cognitive performance with age, while PWHD exhibited a steeper decline compared to both. While both PWH groups had significantly smaller regional brain volumes compared to PWOH, the slopes of volume loss with age were similar across all groups except in the lentiform regions. Smaller brain volumes and increased age interacted for greater cognitive decline in PWHD.
conclusionsPWH who achieve viral suppression do not exhibit accelerated decline in cognition or brain volumes compared to PWOH, while PWHD may be at an increased risk for accelerated cognitive decline. These findings highlight the clinical importance of managing viral load in aging PWH and suggest that once viral suppression is achieved, changes to brain integrity are not accelerated compared to PWOH.
