Design and performance verification of a novel vascular anastomosis connector.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Rapid and safe vascular anastomosis can improve the success rate of surgical procedures and further promote wound healing in patients. Vascular anastomosis connectors (VACs) hold significant potential for facilitating rapid and safe anastomosis. In this study, polylactic acid (PLA) and polycarbonate (PC-ISO) are selected as the materials to prepare VACs. The biomedical properties of the two materials are evaluated, and based on these results, conical thread snap-type VACs are designed. The anastomotic performance of the VACs is assessed using an extracorporeal mock circulation system (MCS). The results show that both PLA and PC-ISO degrade slowly in a simulated body fluid environment, with the sample weight change remaining within 0.37 wt%. Moreover, both materials exhibit good blood compatibility, showing no potential cytotoxicity. In addition, cells adhere well to their surfaces for proliferation, indicating strong biocompatibility. The in vitro MCS simulation tests reveal that both types of VACs can achieve rapid vascular anastomosis, meeting the performance requirements for tensile strength and leak resistance.
