CK5/6-positive, P63-positive lymphoepithelioma-like hepatocellular carcinoma: A case report and literature review.
Article in World journal of clinical cases, 2023. 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
backgroundLymphoepithelioma-like carcinoma (LELC), a rare and unique variant of liver cancer, can be divided into lymphoepithelioma-like hepatocellular carcinoma and lymphoepithelioma-like intrahepatic cholangiocarcinoma. Dense lymphocytic infiltration is its characteristic pathological feature. In recent years, the number of reported cases of this type has increased each year. Studies have shown that lymphoepithelioma-like cholangiocarcinoma occurs more frequently in Asian women; LELC is associated with Epstein-Barr virus infection of liver cells of epithelial origin. Existing research shows that the prognosis of this tumour is good. CASE SUMMARY: A 38-year-old female patient was hospitalized after 3 mo of abdominal pain and nausea. She had been infected with hepatitis B virus more than 10 years prior. The patient was hospitalized on January 21, 2022. Magnetic resonance imaging showed a 36 mm × 28 mm mass under the envelope of the left inner lobe of the liver. No metastasis of lymph nodes or other organs was observed. After left hemihepatectomy, biopsy and immunohistochemistry yielded a final diagnosis of lymphoepithelial hepatocellular carcinoma. After 12 mo of outpatient follow-up and chemotherapy, no tumour metastases were found on the latest computed tomography examination.
conclusionHerein, the patient was treated surgically and then followed up as an outpatient for 12 mo. This case will further expand our overall knowledge of the diagnosis and treatment of this rare tumor.
