A Rare Case of Epstein-Barr Virus-Encoded RNA In Situ Hybridization-Negative Lymphoepithelial Carcinoma With a Nonneoplastic Scar: A Case Report and Literature Review.
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
The etiology of pulmonary lymphoepithelioma-like carcinoma (PLELC) remains unclear. We report the case of an 83-year-old man with a history of smoking who presented without any significant complaints. Computed tomography (CT) performed to investigate emphysema revealed a nodular shadow in the left upper lobe. A subsequent CT performed three months later showed an increase in the size of the nodule, raising suspicion of lung cancer. Thoracoscopic partial left upper lobectomy was conducted, and pathological examination confirmed left PLELC with a granulomatous reaction, classified as pT1bN0M0, stage IA2. Despite negative Epstein-Barr virus (EBV)-encoded small RNA (EBER) in situ hybridization, serum anti-viral capsid antigen immunoglobulin G (VCA IgG) and anti-Epstein-Barr nuclear antigen (EBNA) IgG antibodies were positive, indicating a history of Epstein-Barr virus infection. The postoperative course was uneventful, and the patient was discharged on the sixth postoperative day (POD). No adjuvant chemotherapy was administered, and the patient remained disease-free nine months after surgery. The interplay between scarring and carcinogenesis in PLELC remains poorly understood, highlighting the need for further case investigations.
