More than a "characterizing flavor": Menthol at subliminal levels in tobacco products.
Review in Drug and alcohol dependence, 2024. 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
introductionIn addition to imparting flavor, menthol in menthol-flavored cigarettes enhances nicotine addiction and increases experimentation, initiation, and progression to regular smoking. Menthol can be added to cigarettes at perceptible levels (so-called flavored cigarettes or characterized flavored cigarettes) or non-perceptible levels (subliminal). Our objective was to understand the reasons that tobacco companies use subliminal menthol.
methodsWe identified previously secret internal tobacco company documents dated 1955-2012 in the Truth Tobacco Industry Documents archive on menthol at subliminal levels.
resultsBeginning in at least the 1950s, tobacco companies used subliminal menthol to compensate the flavor loss caused by filters, reduce smoke harshness, reduce dryness, and increase smoke coolness. Varying menthol concentrations were considered to help convert people who smoke non-menthol to menthol brands, possibly because people who use menthol cigarettes have more harship quitting than people who use non-menthol cigarettes.
conclusionsMenthol is an important additive beyond its function as a "characterizing flavor." Tobacco companies use menthol in "non-menthol" cigarettes at subliminal (non-perceptible by the people who smoke cigarettes) levels to improve taste, make them easier to smoke and facilitate initiation, and possibly convert people who smoke non-menthol cigarettes to menthol cigarettes.
