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

In this study, cellulose nanofiber film was modified with methylene blue (MB) dye and vitamin C (Cel/MB/VC). The physicochemical and antibacterial characteristics of the prepared films were investigated. The rate of absorption and release of MB from the prepared film was studied. Films containing MB and VC were used as a kit to detect hydrogen peroxide. The results showed that MB and VC increased the thickness of the film and the elongation of the film. Both MB and VC agents reduced moisture and water vapor permeability, which significantly increased the antioxidant and antimicrobial properties (against Escherichia coli and Staphylococcus aureus) of the film. SEM images showed that the diameter of cellulose fibers is between 20 and 100 nm, which MB and VC completely cover their surface and the surface porosity of the film. FTIR spectra confirmed the electrostatic interactions between cellulose, MB and VC. According to the XRD results, cellulose has a crystalline structure, which is improved further on the vitamin C is added. According to TGA, MB and VC promoted thermal stability of the cellulose films. The release of methylene blue from the film was reported to be 15%. In the presence of H
