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.
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
Pathogens that infect multiple host species have an increased capacity to cause extinctions through parasite-mediated apparent competition. Given unprecedented and continuing losses of biodiversity due to Batrachochytrium dendrobatidis (Bd), the causative fungus of the amphibian skin disease chytridiomycosis, a robust understanding of the mechanisms driving cross-species infection dynamics is essential. Here, we used stage-structured, susceptible-infected compartmental models to explore drivers of Bd-mediated apparent competition between two sympatric amphibians, the critically endangered Litoria spenceri and the non-threatened Litoria lesueurii. We additionally simulated the impact of plausible L. spenceri conservation management interventions on competitive outcomes between these two species. Despite being more susceptible to disease than its competitor, a high relative rate of recruitment allowed the non-threatened L. lesueurii to reach substantially higher densities than L. spenceri in our baseline models, applying a strong absolute force of infection on L. spenceri as an amplifying host. However, simulated management interventions which bolstered L. spenceri recruitment (i.e., captive breeding and release, removal of predatory non-native trout) spurred strong recoveries of L. spenceri while simultaneously (1) increasing the force of Bd infection in the environment and (2) reducing L. lesueurii population density. At high and moderate elevations, combined captive breeding/release and non-native trout removal were sufficient to make L. spenceri the most abundant species. Overall, our results demonstrate the importance of recruitment in moderating pathogen dynamics of multi-host amphibian chytridiomycosis systems. While infection-based parameters are undoubtedly important in Bd management, modifying relative rates of recruitment can substantially alter pathogen-mediated competition between species of an amphibian community.
