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

Polyamide 6 (PA6) can be used as the liner material of a type IV hydrogen storage tank, but its high hydrogen permeability and poor low-temperature toughness limit its application in related fields. In this work, PA6 composites were prepared by introducing graphene with different contents and a nano two-dimensional lamellar filler via the melt blending method, and the effects of the graphene content on the crystallization properties, mechanical properties, and hydrogen barrier properties of the composites were investigated. The results showed that composites containing 2.0 wt% graphene exhibited the best overall performance, and compared with PA6, the crystallization properties, normal-temperature impact strength and low-temperature impact strength of the composites were increased by 16.0%, 130.6% and 111.7%, respectively, and the helium permeability coefficient was decreased by 33.2%. Graphene enhances the crystallinity and lamellar thickness of the composites. Additionally, its two-dimensional lamellar structure can also increase the diffusion path of gas molecules, thereby improving the barrier properties of the composites.
