Squamous Cell Carcinoma Arising in Ungual Lichen Planus: Report and Review.
Article in Skin appendage disorders, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundLichen planus (LP) can lead to severe scarring of the nail unit leading to anonychia. There are very few reports of squamous cell carcinoma (SCC) occurring in the lesions of ungual LP.
objectiveThe aim of this study was to revise the previously reported cases of SCC appearing in ungual LP and to present a new case.
methodsA PubMed search was performed with the terms "nail lichen planus" and "squamous cell carcinoma." Reported cases as well as a new case were depicted in a table.
resultsOnly 2 indexed articles reporting 3 cases were found. All patients suffered of long-lasting scarring ungual LP.
conclusionsThe occurrence of SCC in nail LP is rare. LP is not "premalignant" per se, but SCC might rarely arise in LP scars.
