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

Kenaf cellulose can absorb a considerable amount of water, up to approximately 17.5 wt% of its dry weight at saturation. As the water content increases, the imaginary part of the impedance increases, and dielectric loss in the parallel circuit decreases. Direct current conduction, which exhibits ohmic behaviour at low water concentrations, shows rectification in sample with 6% or more water. This behaviour is attributable to radical electrons, as observed in the electron spin resonance spectra of samples containing water. These phenomena suggest that water exists as a solid rather than a fluid in cellulose. First-principles calculations predict that at saturated water levels, water is fixed as a single molecular quasi-solid layer on the hydrophilic surfaces surrounding the nanofibrils. Consequently, water-adsorbed cellulose can be considered as a solid electronic conductor.
