Spontaneous subarachnoid hemorrhage due to arteriovenous malformation mimicking migraine: A case report.
Article in Radiology case reports, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Subarachnoid hemorrhage (SAH) due to Arteriovenous Malformation (AVM) is a rare emergency case, which is often misdiagnosed as migraine. Here we present a case of SAH due to AVM that mimics migraine. A 41-year-old man came with headaches that radiated to the neck, worsened in the last week, accompanied by nausea, vomiting, photophobia, and a history of intermittent headaches for the previous 2 years. Physical examination was within normal limits, initial laboratory tests showed leukocytosis, and CT scan was not typical. The patient was diagnosed with migraine. Apparently, the lumbar puncture showed very high red blood cells, suspected as SAH. CT angiography revealed an extra-axial AVM. The patient was later diagnosed as SAH due to AVM. We recommend applying 4 key points, namely headache progressivity, neck pain, neck stiffness, and leukocytosis, to differentiate SAH due to AVM from migraine, especially in areas with limited facilities.
