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
Ralstonia solanacearum is a soilborne pathogen that causes bacterial wilt of diverse plant species. To locate and infect host plant roots R. solanacearum needs taxis, the ability to move toward more favorable conditions. However, the specific signals that attract this pathogen were unknown. One candidate is aerotaxis, or energy taxis, which guides bacteria toward optimal intracellular energy levels. The R. solanacearum genome encodes two putative aerotaxis transducers. Cloned R. solanacearum aer1 and aer2 genes restored aerotaxis to an Escherichia coli aer mutant, demonstrating that both genes encode heterologously functional aerotaxis transducers. Site-directed mutants lacking aer1, aer2, or both aer1 and aer2 were significantly less able to move up an oxygen gradient than the wild-type parent strain; in fact, the aerotaxis of the aer mutants was indistinguishable from that of a completely nonmotile strain. Tomato plants inoculated with either the aer2 or the aer1/aer2 mutant had slightly delayed wilt disease development. Furthermore, the aer1/aer2 double mutant was significantly impaired in the ability to rapidly localize on tomato roots compared to its wild-type parent. Unexpectedly, all nonaerotactic mutants formed thicker biofilms on abiotic surfaces than the wild type. These results indicate that energy taxis contributes significantly to the ability of R. solanacearum to locate and effectively interact with its host plants.
