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
Involvement of an oxidative burst, usually related to incompatible plant/pathogen interactions leading to hypersensitive reactions, was investigated with Erwinia amylovora, the causal agent of fire blight of Maloideae subfamily of Rosaceae, in interaction with pear (Pyrus communis; compatible situation) and tobacco (Nicotiana tabacum; incompatible situation). As expected, this necrogenic bacterium induced in tobacco a sustained production of superoxide anion, lipid peroxidation, electrolyte leakage, and concomitant increases of several antioxidative enzymes (ascorbate peroxidases, glutathion reductases, glutathion-S-transferases, and peroxidases), in contrast to the compatible pathogen Pseudomonas syringae pv tabaci, which did not cause such reactions. In pear leaves, however, inoculations with both the disease- and the hypersensitive reaction-inducing bacteria (E. amylovora and P. syringae pv tabaci, respectively) resulted in superoxide accumulation, lipid peroxidation, electrolyte leakage, and enzyme induction at similar rates and according to equivalent time courses. The unexpected ability of E. amylovora to generate an oxidative stress even in compatible situation was linked to its functional hrp (for hypersensitive reaction and pathogenicity) cluster because an Hrp secretion mutant of the bacteria did not induce any plant response. It is suggested that E. amylovora uses the production of reactive oxygen species as a tool to provoke host cell death during pathogenesis to invade plant tissues. The bacterial exopolysaccharide could protect this pathogen against the toxic effects of oxygen species since a non-capsular mutant of E. amylovora induced locally the same responses than the wild type but was unable to further colonize the plant.
