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

Two-dimensional covalent organic frameworks are a unique type of organic crystals with both weak layer-layer interaction and regular one-dimensional nanochannels. Therefore, it is possible to synthesize two-dimensional covalent organic frameworks with reversible stacking phases and thus pore sizes, which hold great potential applications in future nanoelectronics, nanoreactors, intelligent response, gas separation and storage. However, such a goal remains challenging up to now, because the slipped AA-stacking is the most thermodynamically stable phase. Here, we report the realization of shape memory two-dimensional covalent organic frameworks with reversible interlayer stacking sequences, of which AA and inclined phases are induced by the formation of hot ice and the strongly adsorbed organic molecules like Tetrahydrofuran inside the two-dimensional covalent organic frameworks confined nanochannels, respectively. Based on the reversible pore sizes and pore environments, we demonstrate the feasibility of the shape memory two-dimensional covalent organic frameworks in dynamically tunable permeability and intelligent response.
