Therapeutic efficacy of transcranial direct current stimulation in treating auditory hallucinations in schizophrenia: A meta-analysis.
Article in World journal of psychiatry, 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
backgroundSchizophrenia is a chronic psychiatric condition with complex symptomatology, including debilitating auditory hallucinations. Transcranial direct current stimulation (tDCS) has been explored as an adjunctive treatment to alleviate such symptoms.
aimTo evaluate the therapeutic efficacy of tDCS in schizophrenia.
methodsAdhering to PRISMA guidelines, we systematically searched PubMed, Embase, Web of Science, and the Cochrane Library on September 19, 2023, for randomized controlled trials examining the efficacy of tDCS in schizophrenia, with no language or time restrictions. We included studies that compared tDCS with a control condition and reported clinically relevant outcomes. Data extraction and quality assessments were performed by independent evaluators using the Cochrane Collaboration's risk of bias tool. Statistical heterogeneity was evaluated, and a random-effects model was applied due to moderate heterogeneity (
resultsNine studies comprising 425 participants (tDCS group: 219, control group: 206) were included. The meta-analysis demonstrated a significant reduction in auditory hallucination scores following tDCS treatment (weighted mean difference: -2.18, 95% confidence interval: -4.0 to -0.29,
conclusiontDCS significantly reduces auditory hallucinations in schizophrenia, suggesting its potential as an effective adjunctive treatment for managing this disabling symptom. The findings highlight the practical significance of tDCS in clinical settings, particularly for patients with treatment-resistant auditory hallucinations.
