Management of Surgical Margins in the Excision of Oral Leukoplakia: A Scoping Review.
Article in Oral diseases, 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
objectiveTo map the literature on management of surgical margins for oral leukoplakia (OL) and proliferative verrucous leukoplakia (PVL).
methodsSearches were performed in five electronic databases and gray literature. Studies involving patients undergoing any type of surgical excision of OL or PVL were included. Data extraction focused on surgical technique, margin size, method of margin delineation, and recurrence outcome. Margin size was categorized in centimeters.
resultsNinety-one studies were included. More than half of the studies (54.9%) did not report the width of surgical margins. Among those that did, margins between > 2 and < 3 mm were the most frequently reported (19.7%). Notably, 94.5% of the studies did not specify the criteria used to determine the margin width. Furthermore, 76.9% failed to describe the method used to delineate lesion margins. High recurrence was observed in 15.1% of OL cases with surgical margins ≤ 2 mm and in 40% of PVL cases with margins > 2 to ≤ 3 mm. Lesions with margins between 3 and 5 mm showed a lower recurrence rate.
conclusionWe identified a lack of standardization in the reporting of surgical margins. Excision with 5 mm of clinically healthy tissue should be considered the optimal approach for the surgical management.
