Squamous cell carcinoma of unknown origin metastasising to the right atrium causing acute heart failure.
Article in BMJ case reports, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
We describe a case of metastasis to the heart, which was initially suspected to be a myxoma, causing acute right heart failure. Emergency surgery was carried out by opening the right atrium and superior vena cava, and debulking the tumour in a piecemeal fashion, providing temporary relief of symptoms. The histology showed this to be metastatic squamous cell carcinoma possibly of head and neck origin. This is extremely rare, with few published cases. Full endoscopic and CT, including positron emission tomography CT, investigation of the head and neck was performed with no primary findings. Only two such cases of squamous cell carcinoma of unknown origin metastasising to the heart have been described, and, in both cases, the patients died within several weeks of diagnosis. This patient remains alive 2 months postoperatively and is receiving radiotherapy to the chest, but his prognosis remains poor.
