Human Amniotic Membrane Dressing as a Non-Surgical Alternative for Extensive Chronic Ulcers: A Comparative Case Study.
Article in International journal of molecular sciences, 2026. 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
Chronic wound management remains a significant clinical challenge, requiring adaptive therapeutic approaches to achieve wound closure that nonetheless frequently prove fruitless. Balancing the initial pro-inflammatory response with debris removal and tissue rebuilding remains elusive in most cases, leading to pain, drastic quality-of-life deterioration, and, eventually, amputation. Meanwhile, patient adherence is an overarching theme. Furthermore, non-surgical alternatives that effectively promote tissue rebuilding are essential for patients seeking to avoid further invasive procedures. We report a patient with a recalcitrant ulcer managed using human amniotic membrane dressing (hAM-pe) and a bovine collagen matrix (BCM) in spatially distinct areas as an intra-patient control. Methodology included clinical monitoring and ad hoc molecular and histological analyses to assess inflammatory markers and tissue architecture. Following 59 days of observation, the superior evolution of the hAM-pe-treated zone led to the clinical decision to extend hAM-pe treatment over the adjacent BCM area, resulting in total wound closure. The hAM-pe-treated site demonstrated accelerated closure and clinical resolution of inflammation without the presence of a granulomatous response. Molecular analysis revealed downregulated pro-inflammatory mediators (IL-1β, TNF-α, CXCL-10) and upregulated markers associated with angiogenesis (VEGF, CD34) and tissue repair (Arginase-1). In this case, the non-surgical hAM-pe treatment was associated with a favorable healing trajectory, characterized by superior inflammation resolution and enhanced tissue organization (collagen type I/III maturation). While these descriptive findings suggest the potential advantages of amniotic membrane dressings in promoting advanced tissue repair, they remain limited to this individual observation. Further research in larger cohorts is required to validate these mechanisms.
