Refractory hemorrhage in chronic subdural hematoma: primary myelofibrosis with subdural extramedullary hematopoiesis. Illustrative case.

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
backgroundPatients with underlying hematological disorders often experience unexpected intracranial hemorrhage during or after neurosurgical procedures. The authors present a case of underlying myelofibrosis in a patient who experienced recurrent rebleeding within a short period following burr hole surgery for a chronic subdural hematoma, ultimately necessitating decompressive craniectomy. This case highlights the potential challenges of managing hemorrhages in patients with underlying hematological conditions. OBSERVATIONS: A 75-year-old male presented with impaired consciousness. CT revealed a left chronic subdural hematoma, and burr hole surgery was performed. Within 7 days, he experienced three recurrent intracranial hemorrhages, necessitating decompressive craniectomy. Routine blood tests showed no bleeding tendency; however, a detailed evaluation led to the diagnosis of primary myelofibrosis, and multiple extramedullary hematopoiesis was identified in the subdural hematoma. LESSONS: Extramedullary hematopoiesis can occur in the chronic subdural hematoma space, and surgical intervention can lead to severe intracranial hemorrhage. https://thejns.org/doi/10.3171/CASE25255.
