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) provide a polymer platform for exploring covalent linkages to design ordered skeletal and porous architectures. However, the role of linkages in controlling structural and functional evolutions remains to be well explored. In this study, we reported hexaphenyltriphenylene COF photocatalysts constructed with ketazine or azine linkages that differ by a single pinpoint methyl substituent, enabling a controlled interrogation of linkage chemistry. Unexpectedly, the ketazine linkage enhances water uptake, accelerates transport, and directs water confinement within trigonal pores. Simultaneously, it modulates the π-electronic structure through hyperconjugation and inductive/resonance effects, extends light absorption, lowers exciton binding energy, prolongs charge-separated lifetimes, and promotes balanced charge transport. These synergistic structural and electronic evolutions translate into exceptional photocatalysis for hydrogen peroxide production from air and water under ambient conditions. Ketazine-HPTP-COF achieves a production rate of 8.17 mmol g
