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

Cobalt-based catalysts have demonstrated promising performance in both the oxygen reduction/evolution reaction (ORR/OER), positioning them as potential dual-functional catalysts for recharging Zn-air battery. However, the long-standing challenge remains in achieving satisfactory dual-functionality and stability of these cobalt metal centers. Herein, bicontinuous structured nanofibers composed of multiscale cobalt embedded in asymmetric B/N-coordination carbon (denoted as CoBNPCF-900) are constructed, exhibit enhanced ORR/OER activity, and enable the effective operation of zinc-air battery. The utilization of 3D tomograph reconstruction and absolute permeability experiment simulation unravels a "pore connectivity" effect from visualizing the intricate internal porous structure and comprehending the fluid flow within internal passages. Theoretical calculations further elucidate the electronic transfer tendency and spin polarization of CoBNPCF-900, providing a rationale for the improved performance resulting from alterations in the electronic environment surrounding active Co sites embedded in asymmetric B/N-coordination carbon. A homemade rechargeable zinc-air battery using CoBNPCF-900 as the air cathode exhibits a bifunctional overpotential of 0.808 V and a battery lifetime exceeding 1706.6 h, which is superior to that of the Pt/C+RuO
