Gelatin Zymography of Proteases in Chronic Wound Samples.
Article in Methods in molecular biology (Clifton, N.J.), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Cellular processes such as tissue regeneration, inflammation, and migration require the proteolysis of the extracellular matrix and the proteolytic activation of signaling molecules. A widely used and accessible technique for studying these processes is gelatin zymography, particularly for investigating matrix metalloproteinases (MMPs), though it is not limited to them. This method is favored for its simplicity, low cost, and robustness. Despite certain limitations, it remains a preferred approach for the initial investigation of complex samples.Here, we present a protocol applicable to various sample sources, including proteases from human cell lines and bacteria isolated from chronic wounds. We also explore changes in protease activity within exudates from human chronic wounds, a challenging analysis for more complex techniques. Additionally, we emphasize the potential to extend the basic protocol to study the conditions under which proteases are active.
