Nonaneurysmal Perimesencephalic Subarachnoid Hemorrhage as an Atypical Initial Presentation of Cerebral Venous Sinus Thrombosis: A Case Report.
Article in The American journal of case reports, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled it.
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 Subarachnoid hemorrhage is rarely the first presentation of cerebral venous sinus thrombosis. This case study emphasizes the presentation of perimesencephalic subarachnoid hemorrhage due to cerebral venous sinus thrombosis and the importance of neurovascular imaging for reliable diagnosis of nonaneurysmal perimesencephalic subarachnoid hemorrhage due to cerebral venous sinus thrombosis. CASE REPORT We describe a case of cerebral venous sinus thrombosis manifesting initially as subarachnoid hemorrhage. Non-contrast computed tomography showed evidence of subarachnoid hemorrhage involving the prepontine and suprasellar cisterns. Cerebral convexities were totally spared while parenchymal microbleeding was observed in the midbrain. The diagnosis was confirmed by magnetic resonance arteriography and venography. Treatment included low molecular weight heparin and warfarin therapy to restore the international normalization ratio of the patient to 2.5, followed by oral warfarin therapy for 3 months. CONCLUSIONS Cerebral venous sinus thrombosis manifesting initially as subarachnoid hemorrhage is rare. Subarachnoid hemorrhage caused by cerebral venous sinus thrombosis has been reported previously to be confined to the cerebral convexities, sparing the basal cistern. However, this is not always the case where the radiological confirmation suggests the occurrence of nonaneurysmal perimesencephalic subarachnoid hemorrhage.
