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
Xanthomonas campestris pv. vesicatoria (Xcv) is the causal agent of bacterial spot disease of tomato and pepper. Previously, we have reported the adaptation of a recombinase- or resolvase-based in vivo expression technology (RIVET) approach to identify Xcv genes that are specifically induced during its interaction with tomato. Analysis of some of these genes revealed that a citH (citrate transporter) homologous gene contributes to Xcv virulence on tomato. Here, we demonstrate that the citH product indeed facilitates citrate uptake by showing the following: citH is specifically needed for Xcv growth in citrate, but not in other carbon sources; the citH promoter is specifically induced by citrate; and the concentration of citrate from tomato leaf apoplast is considerably reduced following growth of the wild-type and a citH-complemented strain, but not the citH mutant. We also show that, in the Xcv-tomato interaction, the promoter activity of the citH gene is induced as early as 2.5h after Xcv is syringe infiltrated into tomato leaves, and continues to be active for at least 96h after inoculation. We identified an operon containing a two-component regulatory system homologous to tctD/tctE influencing citH expression in Xcv, as well as its heterologous expression in Escherichia coli. The expression of hrp genes does not seem to be affected in the citH mutant, and this mutant cannot be complemented for growth in planta when co-inoculated with the wild-type strain, indicating that citrate uptake in the apoplast is important for the virulence of Xcv.
