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
objectiveThis study examined psychological and trauma-related characteristics of patients with psychogenic nonepileptic seizures (PNES) and explored whether a clinically informed severity grouping distinguished distinct psychosocial patterns. PNES patients were compared with individuals with epilepsy and healthy controls.
methodsParticipants included mild PNES (n = 20), severe PNES (n = 28), epilepsy (n = 48), and healthy controls (n = 50). Assessments measured anxiety, depression, childhood trauma, dissociation, somatization, and alexithymia. PNES severity was defined using clinical indicators such as acute healthcare utilization and ictal motor intensity.
resultsBoth mild and severe PNES groups showed significantly higher anxiety scores than epilepsy patients and healthy controls (p < .01). Depression scores were highest in the mild PNES group and differed significantly from severe PNES, epilepsy, and healthy control groups (p < .05). Trauma profiles varied by severity: sexual abuse was more frequently reported in mild PNES, whereas physical abuse and emotional neglect were significantly higher in severe PNES (p < .05). Mild PNES patients also exhibited higher dissociation, somatization, and total alexithymia scores compared with severe PNES and healthy controls (all p < .05). SIGNIFICANCE: Severity-linked clinical characteristics in PNES were associated with distinct trauma profiles and psychological symptom patterns. These exploratory findings highlighted the relevance of individualized psychological assessment and support the need for further research to validate severity-based distinctions.
