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
The article is devoted to the study of the structure, physico-mechanical properties and biocompatibility of modified conduits based on bacterial cellulose (BC) to replace injured blood vessels. It has been shown that both samples have almost the same elastic recoil and are superior to synthetic vascular grafts in terms of the parameters studied. It should be noted that the first modified sample is characterized by greater elasticity and lower tensile strength compared to the second sample; however, the physico-mechanical properties of the obtained conduits are in the range corresponding to native blood vessels. Scanning electron microscopy (SEM) demonstrated that the conduits under study had a fibrillar structure with nanosized pores that enabled the adhesion of endothelial cells on the internal surface of the vascular implant, improved elasticity under transverse pressure, and raised the elasticity modulus when stretching along the fibrils. Thermogravimetry revealed that elastic recoil formation depended on the nature of polyvinyl alcohol (PVA) interaction with the nanofibrillar structure of BC rather than on the content of polyvinyl alcohol used for modification. The MTT test results confirmed no cytotoxicity and high oxygen permeability in the studied samples, opening great opportunities for their application in regenerative biomedicine to replace injured blood vessels.
