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
Pantoea ananatis is a widespread phytopathogen with a broad host range. Despite its ability to infect economically important crops, such as maize, rice and onion, relatively little is known about how this bacterium infects and colonizes host tissue or spreads within and between hosts. To study the role of motility in pathogenicity, we analysed both swimming and twitching motility in P. ananatis LMG 20103. Genetic recombineering was used to construct four mutants affected in motility. Two flagellar mutants were disrupted in the flgK and motA genes, required for flagellar assembly and flagellar rotation, respectively. Similarly, two twitching motility mutants were generated, impaired in the structure (pilA) and functioning (pilT) of the type IV pili. The role of swimming and twitching motility during the infection cycle of P. ananatis in onion seedlings was determined by comparing the mutant- and wild-type strains using several in vitro and in planta assays. From the results obtained, it was evident that flagella aid P. ananatis in locating and attaching to onion leaf surfaces, as well as in pathogenicity, whereas twitching motility is instrumental in the spread of the bacteria on the surface once attachment has occurred. Both swimming and twitching motility contribute towards the ability of P. ananatis to cause disease in onions.
