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

In this work, we present a modular donor-acceptor strategy that produces oxidatively stable, benzoyl-fused peri-xanthenoxanthene (PXX) ribbons with near-infrared (NIR) emission and light-harvesting properties. Benzoyl fusion at the pseudo-peri positions, achieved through intramolecular Friedel-Crafts planarization, creates the first benzoyl-functionalized PXX monomers, dimers, and trimers that exhibit deep red-NIR absorption and emission without significantly raising the HOMO level. The ribbons display strong, tunable absorption and fluorescence bands, with up to 63% of emission in the NIR and an NIR fluorescence quantum yield reaching 0.36 in solution. Lewis adducts formed between boron-based Lewis acids and carbonyl acceptor sites further enhance the electron-accepting nature of the ketones, producing pure NIR emission (
