Evaluation of Novel Antimicrobial Material to Prevent Biofilm Formation in Medical Devices.
Article in Biomedical instrumentation & technology, 2024. 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
The advancement of novel materials and manufacturing technologies offer opportunities to explore new applications in the space of medical devices. Among these advances, biobased polymers with antimicrobial activity can be used to develop prototypes by additive manufacturing, thereby enabling further exploration with benefits to time and cost. The objective of this research was to assess the effectiveness of polylactic acid (PLA) biopolymer embedded with a copper-based composite (active PLA) to reduce and prevent bacterial growth of microorganisms of concern that may lead to the formation of biofilms. The research was carried out by manufacturing coupons of active PLA using additive manufacturing to test the growth or lack thereof of microorganisms known to form biofilms in medical devices, particularly those with narrow lumens. Testing showed 99.99% antimicrobial effectiveness in reducing Pseudomonas aeruginosa (9027), Escherichia coli (8739), and Klebsiella pneumoniae (4352) growth after 24 hours of exposure. The results confirm the effectiveness of active PLA in preventing microbial growth, which opens the possibility of its use for other medical device applications. Further testing is required, particularly regarding toxicological aspects and potential concerns about the size of copper particles.
