Elevated Galectin-9 across the human brain correlates with HIV neuropathology and detrimental cognitive states.
Article in Journal of neurovirology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
HIV persistence and neuroinflammation are known to contribute to HIV-associated neuropathology. However, the multifaceted pathways driving impairment remain poorly understood. Galectin-glycan interactions have emerged as significant contributors to neuroinflammatory processes and may play a role in neuroHIV. Here, we quantified Galectin-9 (Gal-9), a pleiotropic immunomodulatory protein, in post-mortem brain tissue across multiple regions from HIV-infected and HIV-uninfected donors to determine causal associations with HIV brain injury. We demonstrate that the staining intensity, total staining area, and cell-associated frequency of Gal-9 were elevated, principally in the frontal lobe and basal ganglia. Higher frontal lobe Gal-9 levels correlated with lower pre-mortem neuropsychological performance test scores in areas of attention and motor skills. Our results suggest that Gal-9 activity across the brain plays a role in neuroHIV pathogenesis and constitutes a promising disease-modifying target.
