Environmentally activatable hydrogel for spatiotemporally programmed nitric oxide delivery for diabetic wound healing.

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
Nitric oxide (NO) plays a central role in wound healing, by regulating vascular homeostasis, inflammation, and antimicrobial effects. However, chronic diabetic wounds are difficult to heal due to the hyperglycemic microenvironment, which reduces endogenous NO production. Therefore, developing intelligent dressings capable of spatiotemporally programmed NO delivery holds great promise in promoting diabetic wound healing. Herein, we engineered an environmentally activatable hydrogel that enabled on-demand NO release for diabetic wound healing. The CS-SNAP hydrogel was achieved by covalent grafting of NO donor (S-nitroso-N-acetylpenicillamine, SNAP) onto the matrix of carboxymethyl chitosan methacryloyl (CMCSMA), and by subsequent fast photopolymerization during only 10 s. The CS-SNAP hydrogel enabled sustained release of NO over 300 min by simply modulating ambient light and temperature. When applied to diabetic wounds, not only did the CS-SNAP hydrogel exhibit effective antibacterial activity, but it also showed good angiogenic ability and promoted M1-to-M2 polarization of macrophages. Together, this environmentally activatable platform demonstrates great potential to shorten the inflammatory phase of diabetic wounds, prevent bacterial colonization, and accelerates diabetic wound healing.
