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

Recyclable capture and release of iodine are crucial for environmental issues and the sustainable utilization of iodine. Herein, we present a linkage-engineering strategy in porous aromatic frameworks (PAFs) to regulate iodine adsorption and release. Three PAFs with identical tetraphenylmethane-triazine building blocks but featuring distinct linkages-carbon-carbon single bond (TPM-TTA), secondary amine (TPM-NTTA), and alkynyl group (TPM-ETTA)-demonstrate that the linkage type significantly influences framework properties, including structural defects, porosity, and hydrophilicity, which in turn determine iodine uptake capacity, adsorption kinetics, and recyclability. Among them, TPM-TTA exhibits the highest surface area of 1086 m
