Dermoscopy of external ear melanoma (EEM).
Article in Archives of dermatological research, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
External ear melanoma (EEM) belongs to extremely rare melanoma locations. So far, only single cases of EEM have been described in terms of dermoscopic presentations. This case study report presents dermoscopic patterns of EEM in six patients. The retrospective case study was based on medical documentation (epidemiological, anamnestic, clinical, videodermoscopic, and histopathologic) of consecutive patients who were diagnosed with melanoma located on the external ear between January 2013 and May 2021 in three diagnostic dermatologic centers. In four of six cases, the melanoma was placed on the helix. The histopathological diagnoses included 1/6 lentigo maligna and 5/6 invasive melanomas. The dermoscopic pattern of facial melanoma (FM) was present in 3/6 cases, 1/6 exhibited the typical superficial spreading pattern (one with nodular invasion), 1/6 the multicomponent asymmetric pattern, and 1/6 the hypomelanotic type. Five melanomas presented numerous (3-6) dermoscopic structures characteristic for each dermoscopic subtype. In conclusion, dermoscopy has proved effective for detection of both difficult and easy-to-diagnose EEM, but also in differentiating their dermoscopic subtypes.
