Solitary extrahepatic hepatocellular carcinoma in vertebrae without a primary lesion in the liver might originate from bone marrow: a case report and new hypothesis based on a review of the literature and the latest findings.
Review in Clinical journal of gastroenterology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled it.
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
Solitary extrahepatic hepatocellular carcinoma without a primary lesion in the liver is rare and unique. In such patients, in addition to hepatocellular carcinoma, hepatoid adenocarcinoma, hepatoid teratoma, and hepatoid yolk sac tumor must be considered as differential diagnoses, and patients must be investigated in detail by histopathological studies with immunohistochemistry, especially using epithelial markers for which tumor cells are generally negative in hepatocellular carcinoma. A case with a solitary neoplasm of the vertebrae, which was diagnosed histopathologically as hepatocellular carcinoma, without a primary lesion is presented. The primary lesion was not identified even on autopsy, and the liver was pathologically almost normal. Given the review of the literature and circumstantial evidence, we would like to propose a bold new hypothesis that hepatocellular carcinoma might primarily originate from bone marrow.
