Injectable organic-inorganic hybrid hydrogels for bone defect repair.
Article in Frontiers in bioengineering and biotechnology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
Bone defects caused by trauma, tumor resection, and surgery present significant clinical challenges, often resulting in complications such as delayed union, nonunion, and even long-term functional impairment. Current treatments, including autografts and allografts, are limited by donor site morbidity, immune rejection, and pathogen transmission, highlighting the need for developing reliable synthetic alternatives. To address these challenges, we report a binary composite hydrogel combining gelatin methacryloyl (GelMA) and κ-Carrageenan, reinforced with calcium phosphate cements (CPC). GelMA ensures rapid gelation and biocompatibility, κ-carrageenan improves injectability, and CPC enhances mechanical strength and osteogenic activity, collectively creating a robust and versatile hydrogel system. Furthermore, the hydrogel's injectable, adaptive, and self-healing characteristics enable it to conform to irregular bone defect sites, providing mechanical support and osteogenic stimulation. It also releases bioactive components to accelerate bone regeneration. With exceptional toughness and resilience, this hydrogel recovers its shape after deformation, positioning it as a promising candidate for clinical bone defect repair applications.
