Electrographic Features of Catatonia With or Without Comorbid Delirium.
Article in The Journal of neuropsychiatry and clinical neurosciences, 2026. 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
objectiveCatatonia is an underdiagnosed disorder characterized by speech and motor abnormalities. EEG examinations may improve the accuracy of a catatonia diagnosis, but clinical and electrographic correlations have not been established. The authors describe catatonic features and EEG findings in a large multisite retrospective cohort.
methodsThe clinical records in two health care systems were searched for patients with an EEG recording and a catatonia assessment with the Bush-Francis Catatonia Rating Scale conducted within 24 hours of each other. Included patients were retrospectively screened for delirium through a chart-based assessment. Augmented inverse propensity weighting (AIPW) was used to estimate the causal effects of delirium and catatonia on the presence of an abnormal EEG finding.
resultsOverall, 178 patients met inclusion criteria, 144 (81%) of whom had catatonia. Among the patients with catatonia, 43% also had delirium. EEG abnormalities were present among 43% of patients with catatonia, including 28% of patients with catatonia without delirium and 69% of the patients with co-occurring catatonia and delirium. Individual catatonic signs and EEG abnormalities showed only a weak correlation. In AIPW models, a delirium diagnosis was associated with significantly higher odds for an abnormal EEG finding (OR=6.75; 95% CI=2.83-16.14), whereas a diagnosis of catatonia was not (OR=1.83, 95% CI=0.79-4.24).
conclusionsEEG abnormalities are common among individuals with catatonia, but these are difficult to disentangle from abnormalities resulting from co-occurring delirium. Further research is needed to define the role of EEG examinations in the assessments of catatonia and delirium.
