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
Decellularized tissue-engineered vascular grafts (dTEVGs) exhibit superior biocompatibility, anti-infection properties and repair potential, contributing to better patency and making them a more ideal choice for arteriovenous grafts (AVGs) in hemodialysis compared to chemically synthesized grafts. However, the unsatisfactory reendothelialization and smooth muscle remodeling of current dTEVGs limit their advantages. In this study, we investigated the use of elastase to improve the porosity of elastic fiber layers in dTEVGs, aiming to promote cell infiltration and achieve superior reendothelialization and smooth muscle remodeling. Our findings revealed that elastase treatment induced scattered cracks and holes in the elastic fiber layers of dTEVGs. Porous dTEVGs demonstrated increased cell infiltration in rat subcutaneous tissue. In the rat AVG models, mildly elastase-treated dTEVGs significantly improved cell infiltration and graft remodeling, including adequate smooth muscle cell (SMC) repopulation, impressive reendothelization and regeneration of the extracellular matrix, without stenosis, dilation or disintegration of the grafts. This study demonstrates that porous dTEVGs promote reendothelization, smooth muscle remodeling and extracellular matrix regeneration while retaining a stable graft structure, enhancing durability and puncture resistance in hemodialysis.
