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

Prions are unorthodox infectious agents that replicate by templating misfolded conformations of a host-encoded glycoprotein, collectively termed PrPSc. Prion diseases are invariably fatal and currently incurable, but oral drugs that can prolong incubation times in prion-infected mice have been developed. Here, we tested the efficacy of combination therapy with two such drugs, IND24 and Anle138b, in scrapie-infected mice. The results indicate that combination therapy was no more effective than either IND24 or Anle138b monotherapy in prolonging scrapie incubation times. Moreover, combination therapy induced the formation of a new prion strain that is specifically resistant to the combination regimen but susceptible to Anle138b. To our knowledge, this is the first report of a pathogen with specific resistance to combination therapy despite being susceptible to monotherapy. Our findings also suggest that combination therapy may be a less effective strategy for treating prions than conventional pathogens.
