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
Abstract: BackgroundGlioblastoma (GBM) is an aggressive brain tumor. The authors of this study wanted to find out whether areas of reduced blood flow, called ischemia, that appear after surgery affect how long people live with this disease. To do this, they reviewed scans from 451 patients taken within three days after tumor removal and measured the size of any new areas with poor blood supply. Their results showed that larger areas of ischemia were linked to shorter survival. The prognostic relevance of postoperative ischemia in GBM remains unclear. This study investigated the association between infarct volume and survival in patients with Isocitrate Dehydrogenase (IDH)-wildtype GBM. Methods: We retrospectively reviewed 451 patients with IDH-wildtype GBM who underwent resection between 2013 and 2024 and had diffusion-weighted imaging within 72 h postoperatively. Ischemic changes were defined as new areas of diffusion restriction and stratified into none/rim-only, small (<5 cm³), and large (≥5 cm³) infarcts. Progression-free survival (PFS) and overall survival (OS) were analyzed using Kaplan-Meier and Cox regression models adjusted for age, preoperative KPS, tumor size, extent of resection, MGMT status, adjuvant therapy, and postoperative deficits. Results: Large infarcts were associated with shorter median PFS (7.0 months [95% CI: 5-9]) and OS (14.0 months [95% CI: 9-18]) compared to small infarcts and none/rim-only (PFS: Conclusions: Infarct volume is independently associated with survival in IDH-wildtype GBM. These findings highlight the clinical relevance of postoperative ischemia and may point toward ischemia-related mechanisms as targets for future therapeutic investigation.
