End-of-life care in glioblastoma: A population-based study.
Article in Neuro-oncology, 2025. 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
backgroundThe end-of-life (EoL) phase of care is inevitable for glioblastoma (GBM) patients; however, it lacks standardization. This study aimed to characterize the utilization of care at EoL in GBM patients, focusing on trends over time, regional variability, and the influence of socioeconomic factors.
methodsThis was a retrospective population-based cohort study of all patients with GBM treated in Ontario between 1994 and 2018 using administrative health data and registries available at ICES (formerly the Institute for Clinical Evaluative Sciences). The proportion of patients with palliative care, supportive care, and in-hospital deaths by year of diagnosis was estimated, and trends were assessed with the Cochrane-Armitage trend test.
resultsThe cohort included 9013 GBM patients. There was an increase in supportive care components over the study time period (29.6% in 1994-1998 to 60.2% in 2014-2018; P < .0001). There was a simultaneous decrease in in-hospital deaths (50.5% in 1994-1998 to 21.4% in 2014-2018; P < .001) and hospitalizations within 30 days before death (65.5% in 1994-1998 to 51.7% in 2014-2018, P < .001). This coincided with an increase in chemotherapy administration within 14 days of death and intensive care unit admissions within 30 days of death over the studied period of time. Patient neighborhood income level and geographic location influenced EoL care patterns with regard to both supportive and aggressive components.
conclusionsOver time there was an expansion of both inpatient and outpatient palliative care use at EoL. Rurality and neighborhood income quintile significantly influenced the utilization of these resources, underscoring the need for standardized EoL care practices.
