Effectiveness of electropolishing step on elimination of upstream manufacturing material residues on metallic orthopaedic medical device.
Article in Frontiers in medical technology, 2026. 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
Orthopaedic medical device manufacturing often utilizes manufacturing materials or processing aids that can remain on device surfaces as residues and result in leachable chemicals to which patients can be exposed upon contact with the device. Manufacturing steps that modify a device surface through electrochemical means such as electropolishing can remove manufacturing material residues and be considered as surface "reset" in the manufacturing process. In this report, a retrospective analysis of chemical characterization data gathered for medical devices subjected to electropolishing steps during the manufacturing process is summarized. Review of the extractables data from metallic medical devices demonstrated that electropolishing operations effectively remove the residues originating from manufacturing materials utilized upstream of electropolishing. Based on this retrospective review, electropolishing can serve as a surface "reset" point in the manufacturing process in biological safety evaluations, thereby reducing the overall testing requirements, including animal testing, in alignment with the ISO 10993 framework.
