Efficacy of transcranial direct current stimulation on cognitive function in patients with Parkinson's disease: a systematic review and meta-analysis.
Synthesis in Frontiers in aging neuroscience, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 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
Objective: To assess the therapeutic effect of tDCS on cognitive function in patients with Parkinson's disease. Methods: From the start of the library's construction until June 24, 2024, we searched the following databases for literature: PubMed, Embase, Web of Science, Cochrane Library, China National Knowledge Infrastructure (CNKI), Wanfang, China Science and Technology Journal Database (VIP), and China Biomedical Literature Database (CBM). We also looked through the references in the articles. The improvement of overall cognition in patients with Parkinson's disease with tDCS was the primary outcome indicator. The improvement of executive function, memory, attention, language, quality of life, and depression with tDCS were the secondary outcome indicators. Two researchers extracted data independently, with a third researcher mediating in the event of a dispute. The Cochrane risk of bias tool was used to evaluate the quality of the included literature. Results: A total of 23 articles encompassing 874 subjects were included. tDCS has shown significant efficacy on overall cognition (SMD = 0.73, 95% CI = 0.57 to 0.89, I Conclusion: tDCS demonstrated substantial efficacy in enhancing overall cognition in patients with PD. The efficacy of tDCS was obvious in executive function, language, and depressive mood. Nonetheless, a substantial quantity of rigorous clinical trials on tDCS for cognitive function in patients with PD remains necessary in the future.
