The Significance of Recognizing Myocardial Bridge in the Coronary Spasm Diagnosis in Myocardial Infarction with Nonobstructive Coronary Arteries.
Article in Internal medicine (Tokyo, Japan), 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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 61-year-old man experienced chest oppression for 1 hour. He was positive for troponin T and underwent emergent coronary angiography (CAG), which did not reveal significant coronary stenosis. He was diagnosed with myocardial infarction with nonobstructive coronary arteries (MINOCA). We performed a spasm-provocation test, which revealed a focal spasm at the segment of the myocardial bridge. After receiving a calcium-channel blocker, he exhibited a good clinical course. Coronary spasm is considered an underlying cause of MINOCA; therefore, the presence of a myocardial bridge may help with the diagnosis.
