Reversible cerebral vasoconstriction syndrome (RCVS) caused by over-the-counter calcium supplement ingestion.
Article in BMJ case reports, 2021. 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
A 59-year-old woman was found unresponsive at home. Initial neurologic examination revealed aphasia and right-sided weakness. Laboratory results demonstrated a serum calcium level of 17.3 mg/dL (corrected serum calcium for albumin concentration was 16.8 mg/dL). Extensive workup for intrinsic aetiology of hypercalcemia was unrevealing. Further discussion with family members and investigation of the patient's home for over-the-counter medications and herbal supplements revealed chronic ingestion of calcium carbonate tablets. CT angiogram of the brain revealed multifocal intracranial vascular segmental narrowing, which resolved on a follow-up cerebral angiogram done 2 days later. These findings were consistent with reversible cerebral vasoconstriction syndrome.Appropriate blood pressure control with parenteral agents, calcium channel blockade with nimodipine and supportive care therapies resulted in significant improvement in neurologic status. By discharge, patient had near-complete resolution of neurologic symptoms.
