Association of TRPV1 genetic variants with cognitive functions in Parkinson disease.
Article in iScience, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Parkinson disease (PD) is a neurodegenerative disorder characterized by motor and non-motor symptoms, including cognitive impairment. The transient receptor potential vanilloid 1 (TRPV1) channel has been implicated in neurodegenerative processes, but its contribution to cognitive variation in PD remains unclear. This study aimed to determine whether TRPV1 genetic variants influence cognitive performance and whether these effects are moderated by PD status. Three TRPV1 polymorphisms (rs8065080, rs12936340, rs182637) were genotyped in 274 healthy control subjects and 127 individuals with PD. Cognitive function was assessed across global, executive, visuospatial, memory, attention, and language domains. Moderation analysis revealed that rs12936340 and rs182637 were associated with cognitive performance, and PD status moderated these associations in specific domains. These findings suggest that TRPV1 variation relates to cognitive outcomes in PD and may contribute to individual differences in vulnerability to PD-related cognitive impairment.
