Quantifying Physical Thrombus Characteristics on Cardiovascular Biomaterials Using MicroCT.
Article in Methods and protocols, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Hemocompatibility is a critical consideration when designing cardiovascular devices. Methods of assessing hemocompatibility range from in vitro protein adsorption and static platelet attachment to in vivo implantation. A standard preclinical assessment of biomaterial hemocompatibility is ex vivo quantification of thrombosis in a chronic arteriovenous shunt. This technique utilizes flowing blood and quantifies platelet accumulation and fibrin deposition. However, the physical parameters of the thrombus have remained unknown. This study presents the development of a novel method to quantify the 3D physical properties of the thrombus on different biomaterials: expanded polytetrafluoroethylene and a preclinical hydrogel, poly(vinyl alcohol). Tubes of 4-5 mm inner diameter were exposed to non-anticoagulated blood flow for 1 hour and fixed. Due to differences in biomaterial water absorption properties, unique methods, requiring either the thrombus or the lumen to be radiopaque, were developed to quantify average thrombus volume within a graft. The samples were imaged using X-ray microcomputed tomography (microCT). The methodologies were strongly and significantly correlated to caliper-measured graft dimensions (
