Clinical efficacy of electroacupuncture stimulation based on mismatch negativity in patients with prolonged disorders of consciousness.
Trial report in Arquivos de neuro-psiquiatria, 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
Background: The use of electroacupuncture can regulate brain activity, facilitating consciousness recovery. Objective: To investigate the clinical effectiveness of electroacupuncture at the Cuanzhu (BL2) and Sibai (ST2) accupoints on patients with prolonged disorders of consciousness (DOCs), and evaluate its awakening value. Methods: A total of 48 patients with prolonged DOCs were randomly divided into the control and electroacupuncture groups by the random number table method. The electroacupuncture group underwent treatment at the Cuanzhu (BL2) and Sibai acupoints (ST2) and was given electrical stimulation (2/100 Hz), while the control group received sham electroacupuncture stimulation for 3 weeks. Mismatch negativity (MMN) tests were administered to both groups before and after the intervention. Comprehensive assessments were performed using the Coma Recovery Scale-Revised (CRS-R) and the Glasgow Coma Scale (GCS) to compare the arousal rate and prognosis between the groups. Results: After treatment, both groups of patients showed a significant increase in MMN amplitudes and a reduction in latency ( Conclusion: Electroacupuncture at Cuanzhu (BL2) and Sibai (ST2) may improve consciousness in patients with prolonged DOCs, but its therapeutic effect is not statistically superior to sham electroacupuncture. Due to the present study's small sample size and population heterogeneity, the findings should be interpreted cautiously.
