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
Purpose: This study aims to evaluate the efficacy of Saccharomyces/Rice Ferment Filtrate (SRFF) in mitigating glycation-related skin aging, specifically focusing on the reduction of advanced glycation end products (AGEs) through improved transdermal delivery using nanotechnology and iontophoresis. Methods: We developed a hyaluronic acid (HA) nanogel as a carrier for SRFF, which enhances drug delivery efficiency and stability while providing skin protection. Iontophoresis, a non-invasive electrochemical method, was employed to facilitate the transdermal penetration of SRFF into the skin. An ex vivo skin tissue glycation model was established, and immunohistochemistry and tissue mechanics assessments were conducted to analyze the effects of SRFF combined with HA nanogel and iontophoresis. Results: The combination of SRFF with HA nanogel and iontophoresis significantly reduced the formation of AGEs and mitigated the stiffening effects associated with glycation. The results demonstrated pronounced anti-glycation effects at both the cellular and ex vivo tissue levels. The observed reductions in AGEs and improved skin barrier functionality were likely due to the antioxidant properties of SRFF and its ability to competitively bind to AGEs crosslinking sites. Conclusion: This study highlights the potential of SRFF, in conjunction with HA nanogels and iontophoresis, as an effective method for anti-glycation treatment, reducing AGE accumulation and alleviating skin yellowing and stiffness. The findings support the development of non-invasive, efficacious strategies for enhancing skin health and counteracting the effects of aging.
