A Case of Vasospastic Angina Possibly Triggered by Hyperthyroidism.
Article in Cureus, 2025. 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
A 55-year-old man experienced chest tightness once a month. After half a year, he was admitted to our hospital for a thorough examination due to frequent chest symptoms and was diagnosed with vasospastic angina (VSA) following an ergonovine stress test on coronary angiography. The patient also had hyperthyroidism, which led to a diagnosis of Graves' disease. In this case, the patient did not exhibit typical hyperthyroid symptoms such as goiter, palpitations, excessive sweating, or finger tremors. However, the timing of weight loss coincided with an increase in the frequency of chest pain episodes, suggesting that hyperthyroidism may have contributed to the onset of VSA. Since hyperthyroidism has been reported to be a risk factor for VSA and its coexistence is known to increase the risk of severe coronary spasm, thyroid function should be evaluated aggressively in patients suspected of having VSA.
