Non-right-handedness and psychiatric disorders: A synthesis of epidemiological, genetic, and neurobiological evidence.
Review in World journal of 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
Non-right-handedness (NRH), encompassing left-handedness and mixed-handedness, has been frequently reported at elevated rates in individuals with various psychiatric disorders. The consistency of this association across multiple conditions and its underlying mechanisms is the subject of ongoing investigation. This review synthesized current evidence to explore the association between NRH and psychiatric disorders from epidemiological, genetic, and neurobiological perspectives. We systematically identified and appraised relevant literature investigating NRH prevalence in psychiatric populations and potential explanatory mechanisms. Epidemiological evidence indicates an elevated prevalence of NRH, particularly within neurodevelopmental disorders. Potential contributing mechanisms identified include early developmental disruptions, shared genetic predispositions, and atypical patterns of brain lateralization. While the association between NRH and psychiatric conditions, especially neurodevelopmental disorders, is evident, the causal pathways and relative contributions of identified mechanisms are complex and debated. This review highlighted key areas requiring further research to elucidate these relationships.
