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

High-efficiency antiviral surfaces can be an effective means of fighting viral diseases, such as the recent COVID-19 pandemic. Copper and copper oxides, their nanoparticles (NPs) (CuNPs), and coatings are among the effective antiviral materials having internal and external biocidal effects on viruses. In this work, CuNP colloids were produced via femtosecond laser ablation of the metal target in water, a photophysical, cost-effective green synthesis alternative utilizing sodium citrate surfactant stabilizing the NPs. Raman spectroscopy and X-ray diffraction studies confirmed that the 32 nm mean size CuNPs are mixtures of mainly metallic copper and copper(I) oxide. Polyvinyl butyral was utilized as the binding agent for the CuNPs deposited via high-throughput spray-coating technology. The virucidal efficacy of such coatings containing Cu content ranging from 2.9 to 11.2 atom % was confirmed against animal-origin coronavirus containing ribonucleic acid, the agent of avian infectious bronchitis (IBV), and herpesvirus containing DNA, the agent of bovine herpesvirus (BoHV-1) infection. It was demonstrated that after a short time of exposure, the Cu NP-based coatings do not have a toxic effect on the cell cultures while demonstrating a negative effect on the biological activity of both model viruses that was confirmed by quantification of the viruses via the determination of tissue culture infectious dose (TCID
