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

Aqueous zinc-iodine batteries are attractive for grid-scale energy storage because of their high safety and rate capability. However, conventional hosts for iodine cathodes are often electrochemically inactive and show weak interaction with polyiodides, which not only compromises the battery energy density, but also fails to eliminate shuttle effects. Here we report an electroactive redox coupling strategy to enhance energy density and suppress shuttle effects of zinc-iodine batteries by incorporating ferrocene in cathodes. The ferrocene enables a reversible ferrocene/ferrocenium redox conversion that couples with polyiodides to form insoluble ferrocenium-polyiodide complexes, thereby suppressing shuttle effects. Moreover, this redox elevates the overall discharge capacity of cathodes to 160.5 mAh g
