Psychedelic studies in nonhuman primates: Past and future.
Review in Molecular psychiatry, 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
Studies of serotonergic or 'classic' psychedelics in nonhuman primates (NHPs) have provided valuable information about the drugs' effects on the brain and behavior in closely related species to humans. Psychedelics induce characteristic changes to both spontaneous and operant behaviors in NHPs, though variability exists in the different effects reported by different studies; this variability could be due to factors like differences across drugs, differences in dose ranges across studies, and inter-individual variability in drug responsiveness. Several effects of psychedelics in NHPs mirror those in humans, including development of tolerance to psychedelic effects and low abuse liability, though evidence is mixed on whether psychedelics cause visual hallucinations in NHPs. NHP studies have also examined psychedelic mechanisms of action, supporting and connecting existing findings from human and rodent studies. Here we review the knowledge gained from psychedelic research in NHPs encompassing multiple psychedelic compounds in several NHP species. We conclude by highlighting NHPs' potential to serve as preclinical models of psychedelic effects on psychiatric conditions and suggesting several directions for future research to ensure the accuracy and effectiveness of an NHP psychedelic model.
