TRPM8 Agonist (Cryosim-1) Cream for Chronic Prurigo: A Randomized, Vehicle-controlled Trial.
Trial report in Acta dermato-venereologica, 2025. 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
Chronic prurigo (CP) is a distressing dermatological condition lacking effective topical therapies. This randomized, double-blind, vehicle-controlled trial evaluated the efficacy and safety of Cryosim-1, a TRPM8 agonist cream, in 30 adults with CP. Participants were assigned to apply Cryosim-1 0.1%, 0.5%, or vehicle cream 3 times daily for 4 weeks. Both active formulations significantly reduced Prurigo Activity Score (PAS) compared with vehicle, with 0.1% Cryosim-1 showing a mean PAS reduction of -7.3 (p < 0.001). Significant improvements were observed in 24-h itch intensity, quality of life (DLQI), transepidermal water loss, and stratum corneum hydration. While both concentrations were effective, the 0.1% formulation showed superior tolerability with fewer reports of stinging and erythema. These findings support the potential of TRPM8-targeted therapy in managing CP through dual mechanisms of itch inhibition and skin barrier restoration.
