Unmasking the uncommon: Merkel cell carcinoma mimicking benign upper lip swelling in an elderly patient.
Article in Journal of family medicine and primary care, 2025. 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
Merkel cell carcinoma (MCC) is a rare neuroendocrine carcinoma with aggressive behavior that predominantly affects the sun-damaged skin of the head and neck regions, extremities, and trunk of white older individuals. We present a unique case of MCC presenting as painless upper lip swelling, initially mistaken for a benign lesion. Histopathological examination revealed characteristic features of MCC. Early diagnosis and intervention led to improved outcomes. This case emphasizes the importance of considering MCC in the differential diagnosis of seemingly innocuous cutaneous lesions. To the best of our knowledge, 24 cases of MCC of the lips have been reported to date in the English language literature, and this case is probably the first to be reported from the Middle East region.
