Assessing the long-term effects of microbial therapeutics as treatment within psychiatry: a systematic review.
Synthesis in Frontiers in psychiatry, 2025. 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
Background: The management and treatment of psychiatric disorders by manipulating the gut microbiome and utilizing microbial therapeutics, via modulation of the gut-brain-axis, has been a rapidly growing field of research. Given the novelty of using microbial therapeutics within psychiatry, a growing number of studies have investigated their use as treatment for various psychiatric disorders and symptoms. However, few studies have explored the longitudinal efficacy of these treatments. This review aims to summarize the findings of any studies assessing the long-term effects of gut-related interventions on mood and psychiatric symptoms. Methods: A systematic search of 4 databases (Embase, PsycINFO, Medline, Web of Science) from inception to May 28, 2025, informed by Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, and using key words relating to microbial therapeutics, psychiatric disorders, and long-term effects was conducted. Findings were included or excluded using pre-determined eligibility criteria such as being been written in English and published by a peer-reviewed journal, assessed for quality using the Cochrane Handbook for Systematic Reviews of Interventions Risk of Bias tool, and qualitatively evaluated. Results: The search yielded 4175 studies, of which 1274 duplicates were removed. All remaining studies underwent abstract screening, from which 70 records were full-text screened and a total of ten clinical studies ( Conclusions: Overall, this review highlighted the need for more placebo-controlled studies with larger sample sizes to effectively evaluate the longitudinal potential of microbial therapeutics as treatment for mood-disturbances and psychiatric symptoms. With consideration for the limitations of this field, these results provide evidence that there may be long-term benefits of targeting the gut microbiome as treatment for mood-related disturbances.
