Electroresponsive Thiol-Yne Click-Hydrogels for Insulin Smart Delivery: Tackling Sustained Release and Leakage Control.
Article in ACS applied polymer materials, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Diabetes is a metabolic disorder caused by the body's inability to produce or use insulin. Considering the figures projected by the World Health Organization, research on insulin therapy is crucial. Hence, we present a soft biointerface based on a thiol-yne poly(ethylene glycol) (PEG) click-hydrogel as an advanced treatment option to administrate insulin. Most importantly, the device is rendered electroactive by incorporating biocompatible poly(3,4-ethylenedioxythiophene) nanoparticles (PEDOT NPs) as conductive moieties to precisely control the release of insulin over an extended period through electrochemical stimulation (ES). The device has been carefully optimized on account of: (i) the main interactions established between PEDOT- and PEG-based moieties, which have been studied by density functional theory calculations, and reveal the choice of 4-arm PEG precursors as most suitable cross-linkers; and (ii) the concentration of PEDOT NPs in the device, which has been determined considering minimal interference with the gelation process, as well as the resulting morphological, mechanical, electrochemical, and cytocompatible properties of the PEG-based click-hydrogels. Finally, the management over insulin delivery through ES is verified in vitro, with released insulin being detected by high-performance liquid chromatography. Overall, our hydrogel-based device establishes a method for controlled insulin delivery with the potential for translation to other relevant bioelectronic applications.
