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
Cryogels are macroporous hydrogel scaffolds with promising applications in tissue engineering; however, conventional systems often suffer from inadequate mechanical strength, limited porosity, and biocompatibility concerns due to the use of free radical initiators and organic solvents. In this study, we report the engineering of a hybrid double-network (HDN) cryogel scaffold composed of alginate and poly(ethylene glycol) (PEG), designed for tissue engineering applications. The scaffolds were fabricated via simultaneous cross-linking of alginate and PEG networks at subzero temperatures using a solvent-free and initiator-free biocompatible approach. We systematically investigated the influence of polymer concentration, ice nucleating agents, and sulfation of alginate on the resulting cryogel structure, porosity, and mechanical properties. The optimized HDN cryogels exhibited a highly interconnected macroporous architecture, improved compressive strength, and enhanced elasticity while maintaining cytocompatibility. These findings highlight the potential of HDN cryogels as robust and biocompatible scaffolds for soft tissue engineering and regenerative medicine applications.
