A rare case of recurrent headache during exercise due to severe intracranial atherosclerotic stenosis.
Article in Journal of neurosciences in rural practice. 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
Intracranial atherosclerotic stenosis (ICAS) can cause ischemic stroke, up to 30-50% stroke in Asian population. However, recurrent exercise-induced headache due to ICAS has not been reported. We present a case of a patient 60-year-old male suffering from recurrent headache during exercise due to severe ICAS. The headache occurred after 5 minutes of running, appeared shortly after every running, and resolved at rest. Head magnetic resonance angiography showed moderate bilateral stenosis at middle cerebral artery (MCA), and cerebral catheter angiography confirmed 70% stenosis of the left MCA and 20% stenosis of the right MCA, with robust antegrade flow and good collaterals which explained why there was no neurological deficit. After treated with best medical therapy, including dual antiplatelet, statin therapy, and risk factor modification, for 90 days, he was capable of running for 20 min without headache.
