Styloid-C1 internal jugular vein compression associated with spontaneous cervical epidural hematoma: A case report.
Article in Surgical neurology international, 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
Background: Spontaneous cervical epidural hematoma (SCEH) is a rare condition, and its etiology remains unclear in the majority of cases. Styloidogenic jugular venous compression syndrome (SJVCS) represents impaired internal jugular vein (IJV) outflow between the styloid process and the C1 vertebra and has been associated with several venous hypertension-related disorders, which likely include SCEH. Case Description: A patient presented with an acute SCEH immediately after straining. Imaging revealed a narrow styloid-C1 corridor with the IJV coursing directly posterior to the styloid process (i.e., a retrostyloid configuration). Cervical computed tomography angiogram demonstrated morphologic features suggesting jugular venous compression at the J3 level. Notably, neither an arterial lesion nor an arteriovenous malformation was identified. Conclusion: The anatomical configuration, suspected dynamic venous obstruction, and temporal association with straining supported a venous pathophysiological mechanism resulting in an SCEH attributed to a narrow styloid-C1 corridor with the IJV.
