Accuracy of Conversion Disorder Diagnosis via Telestroke Network Consultation: A Retrospective Cohort Study.
Article in Ochsner journal, 2025. 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: Conversion disorder is a common mimic of ischemic stroke (IS) and transient ischemic attack (TIA). Data comparing the demographic and clinical features of patients with conversion disorder and IS/TIA are scarce, as are data evaluating the accuracy of conversion disorder diagnosis via telestroke consultation. Methods: We retrospectively analyzed consecutive patients evaluated through the Ochsner Health TeleStroke program from April 2015 through July 2016. Cases were classified into 2 categories: IS/TIA or conversion disorder. Patients with other stroke mimics and uncertain diagnoses were excluded. Both initial diagnosis and final diagnosis (following review of all records) were determined. The baseline characteristics of patients with conversion disorder were compared with the baseline characteristics of patients with IS/TIA. Initial diagnosis was compared with final diagnosis, and the diagnostic accuracy of telestroke consultations for conversion disorder was calculated. Results: We evaluated 885 patients with complete data. Of the 254 (28.7%) cases of stroke mimics, 50 cases (19.7%) were conversion disorder, representing 6% of all suspected strokes. We analyzed 616 patients with a final diagnosis of IS/TIA or conversion disorder. Compared to patients with IS/TIA, patients with conversion disorder were more likely to be female ( Conclusion: We found a conversion disorder rate of 19.7% of stroke mimics in the Ochsner Health TeleStroke Network, with a positive predictive value of 0.976 of discriminating conversion disorder from IS/TIA. In our study, patients with conversion disorder were more likely to be female and younger and to have fewer vascular risk factors compared with IS/TIA patients.
