Punctate Porokeratosis Presenting as Multiple Hyperkeratotic Papules on the Bilateral Hands: A Case Report.
Article in Case reports in dermatology. 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
Introduction: Punctate porokeratosis (PK) is a rare variant of PK characterized by small, keratotic papules on the palms and soles. It may occur in adolescence or early adulthood, and it is diagnosed mainly based on the histopathological findings of a cornoid lamella. In this report, we described a case with atypically larger papules and distinct dermoscopic features. Case Presentation: A 36-year-old woman presented with a 1-year history of asymptomatic hyperkeratotic papules on both hands. Physical examination showed multiple, discrete, translucent, hyperkeratotic papules measuring 2-8 mm in diameter (larger than the classic papules of 1-2 mm in diameter) on the palms and fingers. Dermoscopic examination revealed a light red background with yellowish-white scales and irregular vascular structures, whereas the typical "double-track" sign was absent. Conclusion: Histopathological examination is essential for diagnosing punctate PK, particularly in cases where lesions are unusually large or dermoscopic presentations are atypical.
