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

Ion-exchange membranes (IEMs) are essential for efficient and durable flow batteries, yet their inherent conductivity-selectivity trade-off severely limits flow battery performance. Most conventional strategies to improve selectivity rely on regulating ion diffusion within ion-exchange channels through size exclusion and electrostatic repulsion, inevitably compromising ionic conductivity. Here we shift the paradigm to ion partitioning at the membrane-electrolyte interface by establishing ion-specific gating that selectively intercepts active species while preserving rapid charge carrier transport. The developed ultrathin (29 ± 2 µm) polar oxygen-vacancy-enhanced (POVE) membrane suppresses polysulfide crossover through strong chemisorption and a strengthened hydration layer, delivering over 3.4 times the selectivity of the base membrane at comparable conductivity and over 24.8 times the selectivity of commercial Nafion membranes. In the polysulfide-ferrocyanide flow battery, it achieved 82% energy efficiency at 40 mA cm
