1 · What the graph read from it

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.

2 · The registry

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

Cu-DLC coatings were deposited on CoCrMo alloys and silicon wafers using magnetron sputtering. Increasing the atomic percentage (at%) of Cu incorporated into the DLC coatings did not significantly alter their overall structure. However, X-ray diffraction results revealed structural differences with increasing Cu content, including larger crystallite sizes and a transition from a predominantly amorphous structure to a nanocrystalline phase. Significant changes in chemical bonding states were observed through Raman and X-ray photoelectron spectroscopy (XPS). Nanoindentation analysis showed reductions in both hardness and elastic modulus, which were inversely correlated with increasing Cu content. Moreover, the wear rate of Cu-DLC showed a greater decrease at 11.8 at% Cu compared to the other coating. Corrosion analysis further indicated that higher Cu content moderated the corrosion inhibition rate. Time course bacterial killing assays demonstrated that Cu contents between 11 and 15.2 at% in the DLC coatings effectively killed both
