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

Cellulose nanocrystals (CNC), which possessing unique cholesteric liquid crystal properties, can self-assemble and then stack into layered structures to produce structural colouration. By controlling the periodicity of these layered structures, the films with various colors can be fabricated, which could be used as a new generation of environmentally friendly pigments. In this study bamboo-based CNC were utilized as the raw material for constructing vibrantly colored CNC film via layer-by-layer self-assembly process by adding hydroxypropyl cellulose (HPC) to regulate the pitch. By controlling CNC/HPC ratios at 100/0, 92/8, 87/13 and 82/18, the color of the film was in blue, green, yellow and red, respectively. Furthermore, by extending the equilibrium time and adjusting the solvent composition being typically required to allow for the self-assembly, the directional arrangement of the crystalline aggregates was facilitated, resulting in CNC films with more uniform colors and optimized optical and mechanical properties of the films.
