External Auditory Canal Eccrine Hidrocystoma and Equivocal Actinic Keratosis: A Rare Combination and Review of the Literature.
Article in Cureus, 2026. 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
Eccrine hidrocystoma is a rare benign cyst arising from the sweat glands, whereas actinic keratosis is a premalignant cutaneous lesion. Scheuermann's kyphosis is a structural spinal disorder typically identified during adolescence. The coexistence of these conditions has not previously been reported. A patient in their early 70s presented with a blue, dome-shaped cyst located in the deeper portion of the external auditory canal. Surgical excision was performed, and histopathological examination revealed an eccrine hidrocystoma with equivocal features of actinic keratosis. The patient also had a known diagnosis of Scheuermann's kyphosis. Although the hidrocystoma was completely excised, the premalignant potential of actinic keratosis necessitated close clinical follow-up. This rare case underscores the importance of comprehensive histopathological evaluation and vigilant monitoring of potential premalignant lesions. Awareness of such uncommon associations may aid clinicians in optimizing management strategies and ensuring appropriate long-term follow-up.
