Effects of Public Disclosure of a Japanese Celebrity's Oral Cancer: Trends in Oral Cancer Diagnoses.
Article in Oral diseases, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectiveOn February 19, 2019, Chiemi Hori, a renowned Japanese singer, publicly announced her diagnosis of stage IV tongue cancer. The news was widely reported by the Japanese media. This study examined the association between the celebrity's tongue cancer disclosure and trends in the number of oral cancer diagnoses in the national population-based cancer registry (NCR) in Japan.
methodsData from the NCR were used to plot monthly changes in the number of oral cancer diagnoses from 2016 to 2019 according to sex, age, residential area (divided into five categories based on the density of dentists), cancer site, and clinical stage at initial treatment. Time trends were analyzed using Joinpoint regression.
resultsBetween 2016 and 2019, 39,415 oral cancer cases were registered. After Ms. Hori's disclosure, oral cancer diagnoses increased significantly, while other head and neck cancers showed no significant changes. The number of oral cancer diagnoses increased from 784 in January 2019 to 1195 in March 2019 (an average monthly change rate of 8.6% from December 2018 to March 2019).
conclusionsThere has been a sharp increase in the number of oral cancer diagnoses since the celebrity's disclosure. This suggests that it has raised public awareness of oral cancer.
