Article in Molecules (Basel, Switzerland), 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
backgroundPhotoaging, induced by chronic ultraviolet (UV) exposure, is a multifactorial skin disorder characterized by oxidative stress, inflammation, and extracellular matrix degradation.
methodsGl-Gp was extracted and purified from G. lucidum fruiting bodies and structurally characterized for O-glycosidic linkages and O-GlcNAc modifications. Fourier-transform infrared (FT-IR) spectroscopy further confirmed the polysaccharide-protein complex structure of Gl-Gp. A water-in-oil Gl-Gp microemulsion was prepared and assessed in vitro for antioxidant and cytoprotective effects in HaCaT cells, including reactive oxygen species (ROS) reduction, mitochondrial membrane potential stabilization, and apoptosis inhibition. Transdermal penetration was compared with aqueous Gl-Gp. In vivo efficacy was evaluated in a UV-induced rat model by measuring skin morphology, histology, oxidative stress markers, matrix metalloproteinases, and proinflammatory cytokines.
resultsThe microemulsion enhanced Gl-Gp stability and transdermal delivery. In vitro, it reduced ROS, preserved mitochondrial function, and decreased apoptosis in HaCaT cells. In rats, topical application attenuated erythema and epidermal hyperplasia, promoted dermal restoration, increased SOD and GSH-Px activities, and decreased MDA, hydroxyproline, MMPs, and inflammatory mediators.
conclusionsThe Gl-Gp microemulsion exerts antioxidant, anti-inflammatory, and anti-collagen-degrading effects, representing a promising strategy for transdermal delivery and topical prevention of photoaging.
