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
We present a visible-light-driven photocatalytic platform based on a photosensitive metal-organic cage (PMOC), which enables selective recognition and activation of amidyl N─H bonds while suppressing competing homocoupling pathways. This system promotes a controlled intramolecular 1,5-HAT/cyclization cascade via an oxidative proton-coupled electron transfer (PCET) process, using commercially available BPO as oxidant and the in situ generated benzoate anion as the base. Mechanistic studies reveal that the cage architecture serves a dual role-facilitating oxidative PCET and enforcing product selectivity through spatial confinement-which steers the reaction through a unimolecular pathway, effectively inhibiting N─N homodimerization typical of bulk-phase systems. This work establishes cage-confined photocatalysis as a powerful strategy for directing nitrogen-centered radical (NCR) reactivity toward the synthesis of value-added heterocyclic compounds.
