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

It has been challenging to rapidly prepare high-crystallinity covalent organic framework (COF) membranes particularly in large areas because their crystallization often requires extensive time spent on trial and error and screening. Here, we have developed a reverse-phase microemulsion interfacial polymerization to ultra-rapidly prepare COF membranes in tens of seconds. By creating a special ionic liquid/acetic acid aqueous microemulsion, where the reactive monomers are orderly prearranged within the ionic liquid network, the polymerization and crystallization can concurrently proceed at the phase interface under confined spatial conditions. Meanwhile, the water by-products are promptly encapsulated by the reverse-phase microemulsion, significantly accelerating the polymerization reaction. Using the scraping-assisted process, a large-area high-crystallinity TbPa-COF composite membrane (0.4 × 1.0 m) has been successfully prepared, and the TbPa-COF membrane exhibits high permeability (111.3 L m
