Collagen Xerogel Thread Associated With Reduced Inflammatory and Fibrotic Histological Changes During Early Urethral Wound Healing in Rats.
Article in Cureus, 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
Background Early inflammatory and fibrotic responses play important roles in tissue remodeling during wound healing. We developed a novel high-density collagen xerogel thread (CXT) and evaluated its effects on early urethral tissue responses in a rat urethral injury model. Methods A rat urethral incision model was used to compare CXT with conventional absorbable Vicryl® sutures (Ethicon, Inc., Somerville, NJ, USA). Histological evaluation was performed using hematoxylin-eosin staining and immunohistochemical analyses for alpha-smooth muscle actin (α-SMA), connective tissue growth factor (CTGF), and leukocyte common antigen (LCA) on postoperative day 7. Results Compared with Vicryl sutures, CXT was associated with reduced urethral mucosal thickening, lower numbers of CTGF-positive cells and LCA-positive cells, and less prominent stromal α-SMA expression during early wound healing. Conclusions CXT was associated with altered inflammatory and fibrotic tissue responses during early urethral wound healing in rats.
