Clinical and genetic determinants of glioblastoma survival: a retrospective study.
Article in Frontiers in molecular neuroscience, 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
Background: This study analyzed 57 patients with glioblastoma treated at the General University Hospital of Castellon, Spain, focusing on clinical, tumor-specific and genetic factors influencing disease outcome. Variables included age, sex, BMI, extent of surgical resection, and use of radiotherapy or chemotherapy. Tumor characteristics assessed included location, size, proximity to the ventricular system and surgical approach. Genetic mutations in the Methods: Kaplan-Meier survival analysis was used to assess the impact of clinical, tumor-related, treatment, lifestyle and genetic variables on overall survival and progression-free survival, with group differences evaluated using log-rank tests. Given the exploratory nature of the study and the sample size, multivariable modeling was not performed. Patients with IDH1/2-mutant tumors were excluded in accordance with the 2021 World Health Organization (WHO) classification, which no longer defines IDH-mutant grade 4 astrocytomas as glioblastoma. Results: A significant finding was the strong association between extent of resection, tumor proximity to the ventricular system and survival: patients with tumors closer to the ventricles had significantly shorter survival, highlighting the critical role of spatial tumor characteristics in glioblastoma outcomes. Conclusion: These results suggest that integrating clinical, genetic and spatial tumor data into personalized treatment approaches could improve prognosis.
