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

High-valent iron oxo species (Fe(IV)) are attractive for wastewater treatment because of their high selectivity toward organic pollutants in complex water matrices, but their intrinsic redox properties drive rapid quenching by peroxide precursors, causing excessive chemical consumption. This work addresses this challenge by anchoring Fe(IV) on an iron-phthalocyanine-based conjugated organic framework (FePPC) featuring multi-layered reticular structures and strong π-Fe3d-O2p orbital overlapping. The two-dimensional planar structures provided easily accessible active sites and the extended in-plane conjugation fine-tunes the redox reactivity of surface-confined Fe(IV) species, suppressing unproductive decay while preserving selectivity toward diverse pollutants, yielding a 3.2-fold enhancement in Fe(IV) utilization efficiency. Combined experimental and computational results show that the enhanced orbital overlapping delocalizes electrons at the Fe(IV)═O bond and reduces occupancy of its anti-bonding π* orbital, thereby strengthening the bond against nucleophilic attack by peroxymonosulfate, suppressing O
