Elucidating the Phase I metabolism of psilocin in vitro.
Article in Archives of toxicology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Psilocin is a well-studied controlled substance with potential psychotherapeutic applications. However, research gaps remain regarding its metabolism. Our objective was to elucidate a comprehensive Phase I metabolic profile of psilocin to support its forensic management and clinical development. We utilized human enzymes from various sources to characterize the Phase I metabolism of psilocin and estimated its hepatic and extrahepatic clearances via in vitro to in vivo extrapolation. We identified 2-(4-hydroxy-1H-indol-3-yl)-acetaldehyde (4-HIA) as the Phase I intermediate metabolite for the first time. Psilocin was metabolized to 4-HIA by monoamine oxidase A (MAO-A), and further metabolized to the terminal metabolite 2-(4-hydroxy-1H-indol-3-yl)-acetic acid (4-HIAA) by cytosolic aldehyde oxidase (AO) and aldehyde dehydrogenases (ALDHs). MAO-A-mediated hepatic clearance of psilocin (CL
