1 · What the graph read from it

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.

2 · The registry

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

Cooling or the application of mentholated liniments to the skin has been used to treat itch for centuries, yet remarkably little is known about how counter-stimuli such as these induce itch relief. Indeed, there is no clear consensus in the scientific literature as to whether or not cooling does in fact block the transduction of itch signals or if it is simply a placebo effect. This gap in our understanding led us to hypothesize that cooling is antipruritic and, like cooling analgesia, requires function of the cold-gated ion channel TRPM8, a receptor for menthol expressed on peripheral afferent nerve endings. Using a combination of pharmacologic, genetic, and mouse behavioral assays, we find that cooling inhibits both histaminergic and non-histaminergic itch pathways, and that inhibition of itch by cooling requires TRPM8 channels or intact and functional TRPM8-expressing afferent neurons. The cold mimetic menthol is also effective in ameliorating itch in a TRPM8-dependent manner. Moreover, we find that chronic itch can be ameliorated by cooling, demonstrating that this counter-stimulus activates a specific neural circuit that leads to broad itch relief and a potential cellular mechanism for treatment of chronic itch.
