Pentagalloyl Glucose (PGG) Prevents and Restores Mechanical Changes Caused by Elastic Fiber Fragmentation in the Mouse Ascending Aorta.
Article in Annals of biomedical engineering, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 papers.
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
Thoracic aortic aneurysm (TAA) is characterized by dilation of the aorta that can lead to dissection or rupture. Degradation of elastic fibers is a consistent histopathological feature of TAA that likely contributes to disease progression. Pentagalloyl glucose (PGG) shows promise for stabilizing elastic fibers in abdominal aortic aneurysms, but its efficacy and mechanical effects in the thoracic aorta are unknown. We simulated TAAs using elastase (ELA) to degrade elastic fibers in the mouse ascending aorta and determined the preventative and restorative potential of PGG. Biaxial mechanical tests, constitutive model fitting, and multiphoton imaging were performed on untreated (UNT), PGG, ELA, PGG + ELA, and ELA + PGG treated aortas. PGG treatment alone does not significantly alter mechanical properties or wall structure compared to UNT. ELA treatment alone causes an increase in the unloaded diameter and length, decreased compliance, significant changes in the material constants, and separation of the outer layers of the aortic wall compared to UNT. PGG treatment before or after ELA ameliorates the mechanical and structural changes associated with elastic fiber degradation, with preventative PGG treatment being most effective. These results suggest that PGG is a potential pharmaceutical option to stabilize elastic fibers in TAA.
