pH-Responsive Collagen Hydrogels Prepared by UV Irradiation in the Presence of Riboflavin.
Article in International journal of molecular sciences, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
This study reveals the pH-responsive behavior of collagen hydrogels prepared using ultraviolet (UV) irradiation with riboflavin as a photosensitizer. By varying the UV exposure time, we modulated the crosslinking density, thereby influencing the mechanical properties and pH responsiveness. Rheological analysis confirmed successful network formation, whereas swelling studies revealed significant pH-dependent behavior, with maximum swelling at a pH of four and minimal swelling above a pH of six, demonstrating partial reversibility over multiple pH cycles. Mechanical testing showed a pH-dependent elastic modulus, which increased 10 fold from a pH of 6 to 10. Fibroblast proliferation assays confirmed the biocompatibility of the hydrogels, with cell growth positively correlating with the UV exposure time. This research demonstrates the potential of UV-crosslinked collagen hydrogels in biomedical applications, such as tissue engineering and drug delivery, where pH responsiveness is essential.
