Anticoagulation Following Surgery for Glioblastoma: Case Report and Review of the Literature.
Article in Journal of neurological surgery reports, 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
Patients with glioblastoma (GBM) have a high risk of venous thromboembolism (VTE), particularly after surgery, but a competing high risk of intracranial hemorrhage complicates the need for anticoagulation. We present a case of a 70-year-old male on dabigatran with a history of VTE who underwent GBM resection. A preoperative inferior vena cava (IVC) filter was placed to allow for temporary postoperative holding of chemical anticoagulation. Despite this, he developed progressive, life-threatening thromboembolism, including bilateral deep vein thromboses, a pulmonary embolism, and ultimately extensive thrombosis of the IVC extending into the right atrium, causing obstructive shock. This progression occurred despite the resumption of anticoagulation and necessitated a high-risk mechanical thrombectomy, which was complicated by cardiac arrest secondary to right atrial perforation. The patient ultimately survived. Given the questions raised by this case, we review the literature on the use of anticoagulation following surgery for GBM. We highlight the distinct risk profiles associated with prophylactic and therapeutic anticoagulation and suggest early thromboprophylaxis when not contraindicated.
