1 · What the graph read from it

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.

2 · The registry

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

Diabetic skin, a major clinical challenge due to impaired wound healing, is often exacerbated by a hypoxic microenvironment at the wound site. Exosomes have been proven to have excellent biological activities and applied to solve many bioengineering problems. However, the wide application of exosomes is still limited by their short in vitro lifetime and low yield. To overcome these application limitations, this study specifically enhances the pro-angiogenic biological efficacy of exosomes through hypoxic treatment and achieves sustained release using hydrogel loading. In vitro, hypoxia-induced exosomes (Hp-Exo) significantly enhanced endothelial cell migration, proliferation, and angiogenic capacity. In vivo, Gelman hydrogels loaded with Hp-Exo accelerated wound closure, promoted collagen deposition, and increased vascularization in diabetic mice. miRNA sequencing of Hp-Exo revealed that exosomes induced under hypoxic conditions contain various miRNAs, which enhance vascular endothelial cell proliferation, migration, and angiogenesis through the PTEN/PI3K/AKT pathway. These results highlight that hypoxia-induced exosomes, when delivered through a biocompatible hydrogel platform, provide potential therapeutic approach to improve diabetic wound healing by stimulating angiogenesis and tissue regeneration.
