Subarachnoid haemorrhage associated with septic cavernous sinus thrombosis secondary to odontogenic maxillary sinusitis.
Article in BMJ case 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
This case report describes a man in his 50 s who developed septic cavernous sinus thrombosis secondary to odontogenic maxillary sinusitis complicated by a non-aneurysmal subarachnoid haemorrhage (SAH). He presented with visual loss, altered consciousness and shock. CT revealed SAH near the left Sylvian fissure; right maxillary sinusitis and thrombosis of the cavernous sinuses, superior ophthalmic veins and internal jugular veins without an aneurysm. Despite intensive treatment, including broad-spectrum antibiotics, anticoagulants, tooth extraction and endoscopic sinus drainage, he developed a haemorrhagic venous infarction and subsequently died from cerebral herniation due to progressive brain swelling.
