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
Adeno-associated virus (AAV)-mediated gene transfer has demonstrated potential in effectively promoting re-epithelialization and angiogenesis. AAV vector has a safety profile; however, the relatively low delivery efficacy in chronic wound with an inflammatory microenvironment and external exposure has limited its prospective clinical translation. Here, we generated AAV-containing EVs (EV-AAVs) from cultured HEK 293T cells and confirmed that the gene transfer efficiency of VEGF-EV-AAV significantly surpassed that of free AAV. Subsequently, a biomimetic gene delivery system VEGF-EV-AAV/MSC-Exo@FHCCgel developing, and synergistically enhances anti-inflammation and transfection efficiency in the combination of human umbilical cord mesenchymal stem cell-derived exosomes (hUC-MSC-Exo). Upon reaching physiological temperature, this hydrogel system transitions to a gel state, maintaining AAV bioactivity and facilitating a sustained release of the encapsulated vesicles. The encapsulation strategy enables the vesicles to rapidly fuse with endothelial cell membranes, ensuring controlled expression of endogenous VEGF. Results revealed that VEGF-EV-AAV/MSC-Exo@FHCCgel alleviates mitochondrial function in endotheliocyte under oxidative stress. Furthermore, it eliminates senescent macrophages by inhabitation of cyclic GMP-AMP (cGAMP) synthase (cGAS)-stimulator of interferon genes (STING) pathway to promote efferocytosis. The system increases Treg cells accumulation, leading to a reduction of inflammatory cytokines. Collectively, the biomimetic gene delivery system represents a promising multi-faceted strategy for chronic wound healing.
