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) based mixed-matrix membranes with characteristics of molecular-size pores and operation efficiency are promising for gas separation; however, the imbalance between high loading and molecular dispersion impedes the further development of POCs in the field of membrane gas separation. Herein, we propose an in situ cage conversion strategy to construct solid-solution membranes: RCC3, a highly soluble yet nonporous cage, is first synthesized via the reduction reaction, followed by its homogeneous dispersion in PIM-1 to form a uniform membrane. Paraformaldehyde, involved in situ nucleophilic addition, converts nonporous RCC3 to rigid porous FT-RCC3 directly in the membrane. FT-RCC3 membrane exhibits permanent porosity and molecularly dispersed cages with the highest loading (26.6 wt%) achieved ever for POC-based membranes. Permeation measurements of CO
