1 · What the graph read from it

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.

2 · The registry

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

backgroundFunctional neurological disorder (FND) is a common and disabling neuropsychiatric condition in which women comprise approximately 75% of cases. This paper examines whether the gender imbalance seen in FND is unique among neurological and psychiatric conditions and explores the biological, psychological, and social contributors to this disparity.

methodsA narrative review was conducted using MEDLINE, PsycINFO, and Web of Science. Gender ratios were compared across depression, anxiety, post-traumatic stress disorder, schizophrenia, eating disorders, Parkinson's disease, and multiple sclerosis. Evidence regarding sex hormones, early life trauma, gender-based social determinants, and diagnostic biases were synthesized thematically.

resultsAmongst the psychiatric and neurological conditions reviewed, FND shows a pronounced female predominance (approximately 3:1), placing it amongst the most gender imbalanced disorders in our sample, with only eating disorders showing a larger female predominance. Biological factors (particularly the influence of estrogen and progesterone on stress reactivity, neuronal excitability, and agency), may heighten female vulnerability. Social determinants (increased exposure to trauma, socioeconomic inequality, and gender norms) further contribute to this risk. FND shares clinical and demographic similarities with other internalizing disorders and conditions linked to dissociation and trauma. The literature suggests FND emerges from a bidirectional interaction between gonadal hormones and psychosocial stressors.

conclusionsThe marked gender imbalance in FND arises from the interplay of biological vulnerability and gendered social adversity. Understanding these intersecting influences is essential for reducing stigma and guiding future research, diagnosis, and treatment. The findings support the need for a gender-sensitive, biopsychosocial approach to FND care, and investigation.
