EBUS-guided Cryobiopsy-Proven Anthracotic Mediastinal Lymph Node Mimicking Malignancy on FDG PET-CT: A Case Report.
Article in Saudi journal of medicine & medical sciences. 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
Anthracotic mediastinal lymph nodes are an uncommon cause of intense fluorodeoxyglucose (FDG) uptake on positron-emission tomography-computed tomography (PET-CT), often mimicking malignancy and leading to diagnostic uncertainty. Here, we report the case of a 67-year-old Asian male with FDG-avid mediastinal lymphadenopathy that was highly suspicious for metastatic disease. Subsequent endobronchial ultrasound-guided lymph node sampling demonstrated anthracosis without evidence of malignancy or infection. Recognition of this rare benign entity prevented cancer upstaging and unnecessary treatment. This case highlights the importance of histopathological confirmation of PET-positive mediastinal lymph nodes, particularly in patients with suspected or known malignancy, to ensure accurate diagnosis and appropriate clinical management.
