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

Selective extraction of KCl from complex salt lake brines remains a challenging task due to the presence of competing ions and the high energy requirements of conventional separation methods. To overcome these limitations, we have developed a biomimetic separation system that integrates three-dimensional (3D) covalent organic framework (COF) membranes with redox-mediated energy harvesting. These COF membranes are designed with sub-nanometer cavity channels decorated with oxygen-containing groups, which enable fine-tuning of electrostatic potential. This design allows for the simultaneous separation of anions and cations through valence-dependent short-range interactions. By coupling the COF membranes with Ag/AgCl redox pairs, the system converts the salinity gradient across the membrane into an internal electric field, facilitating autonomous ion transport without the need for external energy input. The system achieves over fivefold higher flux rates for K
