Menthol-like cooling compounds, including (R)-(-)-carvone, inhibit the human bitter taste receptors for saccharin and acesulfame K.

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
G protein-coupled receptors (GPCRs) are responsible for sensing sweet, umami, and bitter tastes. Bitter taste receptors belong to the taste receptor type 2 (TAS2R) family, and although trigeminal stimulants, such as menthol, have been reported to reduce bitterness, little is known about whether and how they affect the function of TAS2R. Here, we report that some menthol-like cooling compounds, including (R)-(-)-carvone, act as inhibitors of TAS2R31 and TAS2R43, which are taste receptors responsible for the intrinsic bitter aftertaste of saccharin and acesulfame K. Since (R)-(-)-carvone only exerted a faint cooling effect and a cooling effect is often not preferred in food flavor design, this compound is expected to be highly effective in improving the unpleasant aftertaste of artificial sweeteners. Thus, this study not only provides novel insights into the mechanism by which trigeminal nerve stimulants improve the aftertaste of artificial sweeteners but also useful information for the flavor design of future food products containing artificial sweeteners.
