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

The challenge of designing platinum-based intermetallic catalysts for oxygen-reduction cathodes in fuel cells is to synergistically integrate four critical merits into one catalyst, including fine metal nanoparticles, high ordering degree of intermetallic structure, high Pt content against support and mesopore-rich carbon supports for favourable ionomer dispersion and mass/charge transfers. Here we introduce a radial nanochannel-array carbon sphere (RNCS) support that contains open-through-grooved mesopores with sufficient volume and optimal size. PtCo intermetallic nanoparticles are uniformly assembled into the RNCS to achieve exceptional thermal and electrochemical stability. Annealing at desirable elevated temperatures (>1,000 °C) simultaneously yields highly ordered L1
