To be or not to be a nonhost species: A case study of the Leptosphaeria maculans and Brassica carinata interaction.

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
Leptosphaeria maculans is one of the major fungal pathogens on oilseed rape (Brassica napus), causing stem canker disease. The closely related Brassica species B. nigra, B. juncea, and B. carinata display extreme resistance toward stem canker. In this study, we demonstrate the nonhost status of B. carinata toward L. maculans in France through field experiments and inoculations performed in controlled conditions. A few isolates moderately adapted to B. carinata in controlled conditions were recovered in the field on B. nigra leaves, allowing us to investigate the unusual B. carinata-L. maculans interactions using molecular, macroscopic, and microscopic analyses. A cross between a L. maculans isolate adapted to B. napus and an isolate moderately adapted to B. carinata allowed the generation, in the lab, of recombinant L. maculans strains better adapted to B. carinata than the natural parental isolate obtained from B. nigra, and highlighted the polygenic determinism of the adaptation of L. maculans to B. carinata and B. napus. This biological material will allow further investigation of the molecular determinants of the adaptation of L. maculans to nonhost species and elucidate the genetic resistance basis of B. carinata.
