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
objectivePlant defence against pathogens typically requires salicylic acid (SA) biosynthesis or accumulation or the activation of the SA signalling pathway. However, SA overaccumulation is known to impair plant development, and previous work has shown that SA biosynthesis or signalling can interfere with the activities of plant-beneficial microbes but in a microbial species-dependent manner. This study investigated the effects of endogenous levels of SA in Arabidopsis on the growth-promoting activity of the beneficial rhizobacterium Pseudomonas simiae WCS417r (hereinafter Ps WCS417r).
resultsWild-type levels of SA limited Ps WCS417r-mediated plant growth, as the SA-deficient Arabidopsis mutant sid2-2 accumulated more biomass in response to Ps WCS417r treatment than did the wild-type plants in response to Ps WCS417r treatment, and the SA-overaccumulator cpr5 yielded less biomass than did the wild-type plants. Analysis of previously generated and publicly available plant gene expression datasets revealed modest downregulation of EPS1, a key gene that contributes to SA accumulation, in the roots of Arabidopsis wild-type plants treated with Ps WCS417r. These results suggest that SA accumulation strongly limits the potential of some plant growth-promoting rhizobacteria, potentially minimizing their effectiveness in ensuring sustainable agriculture that is less reliant on chemical fertilizers.
