Biological markers of treatment response to serotonergic psychedelic therapies: a systematic review.
Review in Therapeutic advances in psychopharmacology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper, 1 of them a synthesis that pooled it.
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
Background: Results from contemporary clinical trials of serotonergic psychedelic therapies have led to an increasing focus on their potential clinical use across mental disorders. However, studies examining mechanisms of clinical response to psychedelic therapy in psychiatric populations are limited. This review aimed to synthesize evidence from studies examining biomarkers of clinical response to psychedelic therapies. Data sources and methods: A systematic search of four databases (MedLine, PsycInfo, EMBASE, and Web of Science) for studies investigating treatment response to psychedelic therapies in psychiatric populations that included both clinical outcomes and a related biomarker was conducted on January 10, 2024. Studies were included if they reported on prospective clinical trials involving the use of a psychedelic in participants diagnosed with any Diagnostic and Statistical Manual or International Classification of Diseases mental disorder, where a biological marker was measured and evaluated in association with treatment response. Results: Nine studies investigating the effects of Ayahuasca and psilocybin in major depressive disorder and treatment-resistant depression were included in this review. Several potential biomarkers of response were explored through neuroimaging and blood samples, with significant associations found for serum brain-derived neurotrophic factor, serum C-reactive protein, cerebral activation of the amygdala, and functional connectivity between regions such as the ventromedial prefrontal cortex, anterior cingulate cortex, and posterior cingulate cortex. Conclusion: Results of small studies suggest associations between several putative biomarkers and treatment response to psychedelic therapies. Future trials of psychedelic therapies should integrate biomarker assessment in longitudinal designs to advance the understanding of their mechanism of action in mental disorders. Trial registration: This study protocol was registered to PROSPERO under the number CRD42021291171.
