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

Porous organic cages (POCs) have emerged as promising molecular materials for gas separation and storage due to their discrete, shape-persistent structures and accessible cavities. However, their practical application remains limited by intrinsic instability under harsh chemical environments and difficulties in processing. Here, we report a rapid and efficient interfacial strategy for the fabrication of POCs@polymer core-shell nanostructures that exhibit improved chemical robustness and molecular selectivity. Through chiral self-assembly of enantiomeric cage precursors, well-defined racemic POC particles are synthesized. A non-solvent-induced surface-aimed polymerization (NISAP) technique enables the formation of dense, conformal polyamic acid (PAA) or polyimide (PI) coatings in a single step, yielding stable, monodisperse core-shell nanostructures. These polymer shells confer exceptional acid resistance upon POC particles, as confirmed by etching and PXRD analyses, and significantly alter their pore environments, leading to enhanced selectivity in gas and vapor separation. Notably, the PAA-coated materials achieve a CO
