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

Synthesizing 1D COFs with a tailored chain stacking model is a significant challenge. Here, we introduce a novel preparation approach of 1D COFs involving selective excision from 2D matrix via clip-off chemistry. We carefully designed a 2D sql framework incorporating strategically cleavable olefinic linkers, enabling transformation of X-shaped tetratopic linkers into V-shaped ditopic counterparts through ozonolysis. The resulting 1D COF, featuring carboxyl group, was then functionalized with Anderson-type POMs via Schiff base reactions. This POM-COF composite demonstrated enhanced photocatalytic aldehyde oxidation, benefiting from synergistic effects to achieve efficient and selective conversion of aldehydes to carboxylic acids. Our work offers valuable insights for the custom synthesis of 1D COFs with predefined chain arrangements and functional orientations.
