Mapping the global research landscape and innovations on elderly glioma: a bibliometric analysis.
Article in Frontiers in oncology, 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
Objective: Glioma demonstrates age-specific molecular profiles and heightened aggressiveness in older adults, yet research remains predominantly focused on younger populations. Amid global aging and rising incidence, tailored therapeutic strategies for elderly patients are urgently needed. This study provides a comprehensive bibliometric analysis of scientific literature on glioma in the elderly, aiming to map research output, identify knowledge gaps, and highlight interdisciplinary innovations. Methods: We conducted a systematic search in the Web of Science Core Collection, finding 1,299 relevant publications, and reviewed randomized controlled trials from PubMed to assess clinical progress. We used CiteSpace and VOSviewer to analyze temporal trends, contributions by countries and institutions, collaboration networks, journal impact, co-citations, keyword clusters, and emerging research frontiers. Results: Annual publications increased 4.3-fold from 2001 to 2025. The U.S. (32.8%), Italy (12.4%), and Germany (11.0%) were the leading contributors. Research evolution progressed through three phases: histopathological classification (2001-2013), therapy standardization with radiotherapy/temozolomide (2014-2018), and molecular stratification focusing on MGMT methylation (2019-2025). Key institutions included the University of Zurich and Mayo Clinic. Keyword clustering highlighted aging-related priorities such as surgical management, geriatric assessment, and molecular phenotypes. Conclusion: Significant gaps persist in elderly glioma research, particularly regarding age-related comorbidities and molecular heterogeneity. While clinical trials have established treatment frameworks, future studies should integrate geriatric assessments, tumor microenvironment dynamics, and cross-disciplinary approaches. Dominance by Western institutions underscores opportunities for global collaboration, especially with rapidly aging nations.
