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

We describe a case of a 64-year-old man presenting with squamous cell carcinoma of the external auditory canal as a second primary malignancy after treatment of nasopharyngeal carcinoma, including conventional radiotherapy. Squamous cell carcinoma of the external auditory canal is a rare malignancy, with radiation-related cases even rarer. Management of this malignancy remains difficult due to the critical anatomical location and invasive nature, particularly in advanced stages. Several hypotheses have been advanced to explain the occurrence of second primary malignancies. We discuss this unusual malignancy, highlighting the diagnostic challenges encountered and the potential risk factors associated with second primary cancers.
