Scutellarein promotes diabetic wound repair and preserves fibroblast calcium-mitochondrial homeostasis.
Article in Frontiers in pharmacology, 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: Diabetic wounds are characterized by delayed repair associated with persistent inflammation, oxidative stress, fibroblast dysfunction, mitochondrial injury, and impaired angiogenesis. Scutellarein (SCU), a structurally defined plant-derived flavonoid metabolite, has documented antioxidant and anti-inflammatory activities; however, its role and the mechanistically relevant pathways engaged in diabetic wound repair, particularly those involving calcium-mitochondrial homeostasis and purinergic signaling, remain incompletely defined. Methods: We administered local SCU in a streptozotocin-induced diabetic mouse cutaneous wound model and, in Results: SCU accelerated wound closure and increased re-epithelialization, Masson-positive collagen deposition, proliferative Conclusion: In experimental models, SCU promoted diabetic wound repair and protected fibroblasts from oxidative injury. The data support preservation of calcium-mitochondrial homeostasis as a mechanistically relevant axis, and broad purinergic signaling, possibly involving P2RX1, may contribute to these effects; direct receptor-perturbation studies are warranted.
