Electrochemical corrosion properties of a novel sodium hyaluronate and zinc oxide nanoparticle-coated stainless steel orthodontic arch wire - an in-vitro study.

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
Background: Nanoparticle-based surface modifications of orthodontic arch wires have been extensively investigated for antimicrobial and frictional properties. However, their effect on corrosion behaviour remains largely unexplored. Objectives: To evaluate the electrochemical corrosion resistance properties (corrosion potential [Ecorr], polarisation resistance [Rp], corrosion current density [icorr], corrosion rate [CR] and the impedance-derived charge-transfer resistance [Rct]) of zinc oxide and sodium hyaluronate (ZnO-SH)-coated and -uncoated stainless steel (SS) orthodontic arch wire in three simulated pH environments. Materials and methods: Thirty commercially available 19 × 25" SS arch wires were divided into coated ( Results: The effect of the ZnO-SH coating was strongly environment dependent, with a highly significant coating-to-environment interaction for all rate parameters ( Conclusion: The ZnO-SH coating improved the corrosion resistance of SS orthodontic arch wires in the neutral and alkaline but not in the acidic environment.
