Neurobiological Signatures of Endometriosis: Characterizing Pain, Cognition, and Brain Morphology.
Article in bioRxiv : the preprint server for biology, 2026. 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
Endometriosis affects approximately 10% of reproductive-age women worldwide and is associated with substantial pain and mental health burden, yet its neurobiological correlates remain poorly characterized. Neuroimaging studies of endometriosis are particularly limited. Here we present a comprehensive, multidimensional investigation of the neurobiology of endometriosis, integrating structural and diffusion neuroimaging, biofluid measures, neuropsychological testing, and detailed health and psychosocial phenotyping in individuals with and without endometriosis. Compared with controls, individuals with endometriosis exhibited higher levels of pain, depression, and anxiety and performed worse across multiple cognitive domains. Global and regional brain morphometric measures did not differ between groups; however, endometriosis-specific pain was associated with altered gray matter volume and white matter microstructure across distributed pain-related neural circuits. These findings identify pain-related neurobiological signatures of endometriosis and establish a foundation for mechanistic and translational studies of its central nervous system effects.
