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

Ionomer adsorption-induced Pt poisoning and high local oxygen transport resistance constitute two critical challenges preventing proton exchange membrane fuel cells from achieving low-Pt loadings. Yet, strategies concurrently mitigating both issues remain limited, making it challenging to achieve satisfactory performance in both kinetically controlled low-current-density and mass transport-controlled high-current-density regions. Herein, we show that this limitation can be addressed with a mesoporous carbon support design whose key lies in constructing a small mesopore-dominated structure while rationally controlling pore depth to a medium level. This design creates an ideal local reaction environment for Pt nanoparticles inside the mesopores, one that protects most Pt from ionomer poisoning while achieving efficient oxygen diffusion. Using the developed carbon support, we synthesize an intermetallic PtCo nanocatalyst that delivers competitive membrane electrode assembly performance at low-Pt cathode loading (0.1 mg
