External auditory canal sebaceous carcinoma.
Article in BMJ case reports, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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 incidence of sebaceous carcinoma (SC) in the outer one-third of the external auditory canal is considered extremely rare, and only eight case reports have been published. We present a case of a male patient in his late 70s known case of hypertension on indapamide. His medical history included a postspinal tumour that had been treated with surgery and radiation more than 40 years ago and current complaints of right ear pain and purulent discharge. A right ear soft granular tissue mass was found. Complete debulking of the right ear mass was done in conjunction with middle ear exploration, moderately differentiated SC diagnosis was made based on the histopathological analysis. The patient was free of recurrence but then died of an unrelated pulmonary infection. SC should be suspected in elderly patients who present with long-term complaints of a mass with or without otalgia, and these patients should be examined for the presence of such tumours especially if they report a history of radiation. Additionally, more research is warranted to investigate the association of diuretics with SC.
