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

Direct ethanol fuel cells are promising clean energy devices, but the difficulty in cleaving the C─C bond of ethanol leads to low C1 pathway selectivity (typically ∼10%) and incomplete energy conversion. To address this challenge, we synthesized a porous multiphase Pd-based metallene nanocatalyst co-doped with oxygen-philic Cu and W. Temperature was identified as the key factor regulating the crystal structure: low temperatures yielded amorphous phases, high temperatures produced crystalline phases, and intermediate temperatures formed the desired crystalline/amorphous mixed multiphase structure. This multiphase structure provided abundant active sites. The optimal PdCuW metallene exhibited exceptional performance for ethanol electrooxidation: a record-high C1 pathway selectivity of 72.6% (1.6 times that of undoped Pd metallene and 10.2 times that of commercial Pd/C), a mass activity of 4301.6 mA/mg
