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

This work presents the results of deposition by magnetron sputtering nanostructured multilayer Cr/(Cr/a-C)ml coatings on AISI 316L and AISI 321 steel substrates. Chemical compositions were confirmed through EDX analysis with scanning electron microscopy. The coating thickness was measured with Calotester (KaloMAX II) and the total thickness of the coatings obtained ranged from 1.684 ± 0.193 μm for AISI 316L to 1.749 ± 0.123 μm for AISI 321. A Daimler-Benz Rockwell indentation test for adhesion quality and a nanoindentation test with a Berkovich indenter were carried out. According to the Raman spectroscopy analysis and in agreement with mechanical tests, it is supposed that it is the formation of a diamond-like carbon phase which enhances the mechanical properties. The hardness values obtained for the nanostructured multilayer Cr/(Cr/a-C)ml coatings were improved compared to those of the base stainless steels.
