Repetitive transcranial magnetic stimulation guided by event-related potential P300 application in schizophrenia.
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 1 paper.
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
backgroundRepetitive transcranial magnetic stimulation (rTMS) entered clinical practice in China after 2000, first used in psychiatric surgery, and then in neurology and other disciplines. The First Hospital of Jiaxing introduced TMS in 2015. In practical applications, it has been found that different models of instruments and technical parameters can lead to differences in therapeutic efficacy. Therefore, our hospital selected the Danish TMS instrument, which ranks second in China, to test patients with schizophrenia from March 2021 to July 2021, with a focus on comparing the results at 5 Hz, 10 Hz, and 15 Hz. The testing time is concentrated between 8:30 to 10:30 in the morning. A contingency plan was made for the quality after inspection before testing. Two evaluators independently control the quality of the contingency plan. The data is independently saved and proofread by two evaluators. The purpose of this study is to translate the research results into clinical practice and provide reference basis.
aimTo investigate the effects of rehabilitation therapy using rTMS on the negative symptoms and event-related potential component of P300 in chronic schizophrenia.
methodsOne hundred and five patients with chronic schizophrenia were randomly allocated to three groups based on the frequency of rTMS (5, 10, or 15 Hz). The patients underwent five sessions of rTMS per week for 5 weeks. We compared the pre- and post-treatment P300 latency and scores for the Scale for Assessment of Negative Symptoms (SANS).
resultsA significant decrease in SANS score after rTMS was observed in the 10-Hz group (
conclusionrTMS at 10 Hz improved negative symptoms and cognitive function in chronic schizophrenia; however, further studies on the mechanism of action are required to validate our observations.
