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

Proton exchange membrane fuel cells feature considerable scalability advantages over lithium-ion batteries for heavy-duty-vehicle applications. The different driving behaviours and operating conditions of heavy-duty vehicles pose challenging requirements, particularly on fuel cell lifetime and efficiency. Here we report the design of a graphene-nanopocket-protected, pore-confined and electrochemically accessible Pt nanocatalyst supported on Ketjenblack carbon for heavy-duty-vehicle applications. The membrane electrode assembly made from these nanocatalysts delivers an initial mass activity of 0.74 A mg
