Hepatic angiomyolipoma, misdiagnosed as hepatocellular carcinoma.
Article in Journal of surgical case reports, 2023. 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
Perivascular epithelioid cell neoplasm (PEComa) is a rare type of tumor, and hepatic PEComa is even rarer. Its preoperative diagnosis is difficult, given the absence of specific clinical manifestations, often constituting an accidental finding, and the lack of a gold standard for identification using imaging studies. Instead, the diagnosis of hepatic PEComa is based on morphological and immunohistochemical features. We describe a case of an asymptomatic hepatic PEComa, angiomyolipoma type, which appeared in a middle-aged woman with chronic liver disease, during her follow-up and screening. Given the patient's context, human immunodeficiency virus-positive with chronic hepatitis C, and the similarities between the two tumors, the hepatic lesion was interpreted as hepatocellular carcinoma. The patient underwent surgical excision of the tumor, and the positive immunohistochemical staining for human melanoma black 45 and Melan A made the definitive diagnosis. In the absence of aggressiveness tumor markers, surveillance was decided. We also provide a literature review of these tumors.
