Global trends and emerging hotspots in neuromyelitis optica spectrum disorder diagnostic research: A bibliometric analysis.
Review in Medicine, 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
backgroundNeuromyelitis optica spectrum disorder (NMOSD) is a rare autoimmune inflammatory disease of the central nervous system characterized by recurrent optic neuritis and longitudinally extensive transverse myelitis, frequently leading to severe and irreversible disability. Over the past decade, advances in diagnostic criteria, serological testing, and biomarker research have substantially transformed the diagnostic framework of NMOSD. However, a comprehensive bibliometric analysis focusing specifically on diagnostic research in this field has been lacking.
methodsPublications related to NMOSD diagnostic research published between 2016 and 2025 were retrieved from the Web of Science Core Collection. After refinement of the search strategy and manual screening based on predefined relevance criteria, bibliometric analyses were performed using CiteSpace, VOSviewer, and the Bibliometrix package in R to evaluate publication trends, international collaboration patterns, co-citation networks, and evolving research hotspots.
resultsA total of 2029 publications were included. Annual publication output and citation counts increased steadily throughout the study period, reflecting sustained expansion of academic interest. China was the leading contributor, with strong collaborative links to the United States and the United Kingdom. The 2015 international consensus diagnostic criteria emerged as the most influential reference, serving as a foundational framework for subsequent research. Co-citation and keyword analyses demonstrated a clear shift from an early focus on disease definition and differential diagnosis toward biomarker-guided and technology-enabled precision diagnosis. Current research frontiers include optimization of aquaporin-4 immunoglobulin G detection platforms, astrocytic injury biomarkers such as glial fibrillary acidic protein, inflammatory mediators including interleukin-6 and complement components, magnetic resonance imaging- and optical coherence tomography-based neuroimaging markers, and multimodal diagnostic assessment.
conclusionNMOSD diagnostic research has transitioned from consensus-driven classification toward integrated, multimodal precision strategies. Continued international collaboration and biomarker standardization will be essential to improve early diagnosis and clinical management.
