Neurocognitive Function and Quality of Life After Multifraction Radiosurgery for Large Resected and Intact Brain Metastases: Results of a Prospective Clinical Trial.
Article in Advances in radiation 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
Purpose: Stereotactic radiosurgery (SRS) is the standard of care for brain metastases, providing effective local tumor control while avoiding the neurocognitive effects of whole-brain radiation therapy. However, large brain metastases have been excluded from the randomized studies of single-fraction SRS, and there are limited data regarding neurocognitive outcomes with multifraction radiosurgery approaches for large intact or resected brain metastases. Methods and Materials: We performed a prospective phase 1 dose-escalation study of multifraction SRS for intact or resected brain metastases 3 to 6 cm in diameter from 2012 to 2021. Patients longitudinally completed the Hopkins Verbal Learning Test (HVLT), Mini-Mental State Examination, Functional Assessment of Cancer Therapy-Brain, and Medical Outcomes Cognitive Scale. Reliable Change Index is used to assess HVLT change from baseline to 4 months. Significance is defined as greater than 1 SD change. Analysis of variance comparisons were performed for clinicodemographic characteristics associated with neurocognitive outcomes or quality-of-life metrics. Results: Of the 24 patients treated in the trial, 15 completed both baseline and 4-month neurocognitive assessments. For the 15 patients with neurocognitive assessments, median age was 57 years (range, 37-74 years), median baseline Karnofsky Performance Status was 80 (range, 70-90), and median volume of radiation target was 15.9 cm Conclusions: Of the evaluable patients with large brain metastases treated with dose-escalated, multifraction SRS, the majority of patients demonstrated stable or improved neurocognitive function and quality of life in follow-up.
