1 · What the graph read from 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.

2 · The registry

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

This report presents a rare case of bronchogenic adenocarcinoma with initial metastasis in the external auditory canal. The patient, a 64-year-old man with a history of bladder urothelial carcinoma, initially presented with a persistent right otitis externa. Otoscopic examination revealed a mass obstructing the right external auditory canal. The temporal bone computed tomography scan revealed a mass that completely obstructed the right external auditory canal and extended into the middle ear. A biopsy showed a poorly differentiated adenocarcinoma of bronchogenic origin, confirmed by positive immunohistochemical staining for cytokeratin 7 and Thyroid transcription factor-1. Further imaging revealed a large tumor mass in the lung involving the mediastinum and parenchyma, along with carcinomatous lymphangitis and cerebral metastasis. Histopathological examination of the primary lung tumor confirmed a poorly differentiated adenocarcinoma with similar features to the metastasis in the external auditory canal. The tumor was staged as T4N2M1c, and the patient underwent local external-beam radiation therapy with chemotherapy.
