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

Efficient gas transport and abundant triple-phase boundaries (TPBs) are vital for thick cathode catalyst layers (CCLs) in proton exchange membrane fuel cells (PEMFCs), yet remain challenging to realize. In this work, we introduce a carbon-based nanotrap architecture functionalized with pyrrolic-N groups, which reorganizes the Pt-carbon-ionomer interface to enhance local oxygen supply. These nanotraps simultaneously confine Pt nanoparticles and ionomer, forming continuous pathways for oxygen, protons, and electrons, thereby significantly increasing active TPB density. The underlying enhancement mechanism is validated by x-ray tomography and 3D two-phase flow simulations. Using a 15.5 µm-thick CCL, the optimized electrode achieves peak power densities of 1940 mW cm
