Headache and Papilledema Unmasking an Underlying Myeloproliferative Neoplasm: A Case of Chronic Recanalized Cerebral Venous Sinus Thrombosis.
Article in Cureus, 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
Cerebral venous sinus thrombosis (CVST) is a potentially life-threatening condition that can present with clinical features mimicking idiopathic intracranial hypertension (IIH), as both may present with headache and bilateral papilledema, leading to diagnostic uncertainty. We report a case of a 50-year-old woman referred for suspected IIH in whom venous neuroimaging revealed chronic, partially recanalized CVST. Thrombocytosis on full blood count, previously uninvestigated, prompted hematological assessment and led to the diagnosis of a JAK2-positive myeloproliferative neoplasm, for which cytoreductive therapy was initiated alongside anticoagulation. This case underscores the importance of performing venous imaging in patients with headache and papilledema, even when features suggest IIH, and highlights that thrombocytosis should prompt evaluation for an underlying myeloproliferative disorder to guide long-term management and prevent recurrent thrombosis.
