Bilateral radiation-induced squamous cell carcinoma of the external auditory canal: the effect of immunosuppressive therapy.
Article in The Journal of laryngology and otology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundSquamous cell carcinoma of the external auditory canal is rare, with bilateral cases even rarer. We report the management of a patient with bilateral external auditory canal squamous cell carcinoma related to radiotherapy and immunosuppression. CASE REPORT: A 47-year-old woman with a history of radiotherapy 14 years prior and renal transplantation 6 years prior presented with bilateral external auditory canal squamous cell carcinoma. Squamous cell carcinoma was excised with a purely surgical approach. The two operations included a tympanic membrane graft to preserve hearing on the left side. The patient remains disease-free six months post-op. She uses a bone-conduction hearing aid to good effect on the right side and has mild hearing loss on the left. The operative areas have healed well. DISCUSSION: The patient's previous radiotherapy and immunosuppression may have contributed to her bilateral external auditory canal squamous cell carcinoma. Preventative positron emission tomography scans have the potential to identify second malignancies early, allowing more conservative treatment plans.
