Pre-clinical Evaluation of Wound Healing Efficiency of Biomedicine-Responsive Patch Overlay on Polymeric Matrix: A Comparative Study.
Article in Aesthetic plastic surgery, 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
backgroundWound healing is a complex biological process requiring effective therapeutic strategies to promote tissue regeneration and angiogenesis. This preclinical study evaluates the efficacy of two newly formulated bio-polymeric patches (Sample 1 and Sample 2) in comparison to a standard treatment (Tegaderm-3M) and an untreated control, using a full-thickness excisional wound model in Swiss albino mice.
methodsTwenty-four healthy adult male mice were randomly allocated into four groups (n = 6/group). Following ethical approval (Ref: AU/SOHMS/DOPT/2024/CCSEA/P05), standardized wounds were created, and treatments were administered accordingly. Wound progression was documented photographically on Days 0, 3, 7, and 10, and tissue samples were analyzed histologically using Hematoxylin & Eosin, Masson's Trichrome, and CD31 immunohistochemistry.
resultsResults demonstrated significantly improved wound closure, reduced inflammation, enhanced collagen deposition, and greater angiogenesis in treated groups, particularly in Sample 2. By Day 10, Sample 2 exhibited near-complete epithelialization, mature dermal architecture, and robust CD31-positive endothelial cell presence, indicating enhanced neovascularization. Compared to the control, which showed delayed healing, poor collagen organization, and minimal angiogenesis, both treated samples and the standard group showed superior outcomes in terms of tissue restoration and remodelling. Histological evaluations confirmed Sample 2's superiority in promoting early re-epithelialization and dense collagen matrix formation, while immunohistochemical data supported its pro-angiogenic potential.
conclusionIn conclusion, the bio-polymeric patch represented by Sample 2 significantly accelerated wound healing, demonstrating outcomes comparable to a commercial standard. These findings support its potential as a promising candidate for advanced wound care therapeutics in clinical applications.
