Laugier-Hunziker Syndrome Diagnosed by a Medical Student After Multiple Failed Specialist Evaluations: A Case Report.
Article in Cureus, 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
Laugier-Hunziker syndrome (LHS) is a rare, benign acquired pigmentary disorder characterized by mucosal macules that can resemble more serious systemic disease. We describe an 82-year-old woman with a four-year history of progressive oral hyperpigmentation involving the lower lip, buccal mucosa, and gingiva, with sparing of the tongue and upper lip, in whom repeated specialist evaluations had not yielded a diagnosis. A comprehensive clinical assessment in a family medicine clinic, including review of prior negative systemic workups, led a third-year medical student to recognize the pattern as LHS. The patient also reported similar pigmentary changes in her mother around the time of a lymphoma diagnosis, raising the possibility of familial or environmental influences, although no causal association could be established. This unusually late-onset presentation underscores the need to consider LHS in elderly patients with unexplained oral pigmentation and highlights the value of attentive history-taking and examination in primary care.
