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

Covalent organic frameworks (COFs) are emerging crystalline porous materials with precisely defined architectures and tunable chemistry, offering strong potential for next-generation gas separation membranes. This review provides a material-centric perspective on COF-based membranes, emphasizing how framework design governs molecular transport behavior. We discuss key structure-property relationships in COF synthesis, highlighting the roles of crystallinity and chemical functionality in regulating selective transport. Recent advances in synthetic methods are compared in terms of framework order, pore alignment, and scalability. The evolution of COF membrane fabrication is then reviewed, from mixed-matrix systems to in situ grown and freestanding membranes, with attention to interfacial engineering, mechanical stability, and orientation control. Fundamental transport mechanisms are summarized to connect pore chemistry with separation performance. Application-focused progress in CO
