Global Dynamic Impression for Differentiating Between Epileptic and Psychogenic Nonepileptic Seizures: A Feasibility Study.
Article in Brain and behavior, 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
objectiveMedical personnel show difficulty in differentiating psychogenic nonepileptic seizures (PNES) from epileptic seizures (ES). The purpose of this study was to conduct an initial feasibility assessment of the global dynamic impression (GDI) principle and to evaluate its effectiveness in enabling the diagnosis of epileptic versus psychogenic seizures using video footage of events, even by untrained personnel
methodsWe based this study on video footage showing five videos of PNES and five ES videos. We asked physicians and nurses from the emergency department, internal medicine department, neurology department, and medical students to classify the videos before and after learning the GDI principle. The GDI principle is a simple clinical tool assuming repetitive movements with minimal dynamics in vector and frequency in motor PNES. A correct answer earned a score of 10 points, and a wrong answer a score of 0. Therefore, the questionnaire score could range from 0 to 100.
resultsA total of 108 medical personnel participated in the study. A total of 42 participants filled out the questionnaire before training-Group 1, and 36 participants filled out the questionnaire after training-Group 2; 30 participants filled out the questionnaire before and after the training-Group 3. The mean score of Group 1 was 55.23 ± 17.83 versus 75.55 ± 13.61 in Group 2 (p = 0.0000001). The mean score of Group 3 was 53 ± 17.8 compared to 78 ± 12.9, before and after training, respectively (p = 0.000001). SIGNIFICANCE: A brief training on the GDI principle of various medical teams, even unskilled teams, significantly improves differentiating PNES from ES.
