Phase-dependent responsiveness in soft porous crystals assembled from flexible metal-organic cages.
Article in Chemical science, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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.
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
Soft porous crystals (SPCs) based on flexible metal-organic cages (MOCs) remain elusive due to challenges in preserving both dynamic behavior and crystallinity after desolvation. Here, we report an SPC assembled from flexible metal-organic cages (MOCs), in which the resulting porous properties, either conventional microporous filling or gate-opening behavior, depend on the activation process. The flexible MOCs are constructed by a covalent linking strategy; amine-functionalized dirhodium paddlewheel complexes serve as building blocks and are connected with aldehyde units through Schiff base condensation. By systematically tuning ligand substituents, axial pyridine coordination, and activation conditions, we achieve a delicate balance between crystallinity and flexibility. Notably, one compound provided two distinct activated phases under different activation conditions. Their structures were determined by three-dimensional electron diffraction (3D ED). One phase displays a conventional type I CO
