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

Chronic wasting disease (CWD) is an expanding prion disease of cervids. CWD prions persist in the environment, are shed in excreta, and accumulate in tissues of infected cervids, raising concerns about its zoonotic potential. Using cynomolgus macaques, we explored the zoonotic potential of CWD. Although most inoculated macaques remained asymptomatic, sensitive in vitro prion amplification assays revealed low levels of prions in macaque tissues. Inoculation of transgenic mice and bank voles with macaque tissues induced prion disease, achieving 100% transmission rates upon serial passage. One interpretation of these findings is that CWD prions retain infectivity across species and that primate infection may manifest atypically while still enabling transmission. Our results challenge earlier conclusions that minimize the zoonotic risk of CWD and underscore the need for continued surveillance.
