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
Pepper SAR8.2 gene (CASAR82A) was previously reported to be locally or systemically induced in pepper plants by biotic and abiotic stresses. In this study, the physiological and molecular functions of the pepper SAR8.2 protein in the plant defense responses were investigated by generating Arabidopsis transgenic lines overexpressing the CASAR82A gene. The transgenic Arabidopsis plants grew faster than the wild-type plants, indicating that the CASAR82A gene was involved in plant development. The ectopic expression of CASAR82A in Arabidopsis was accompanied by the expression of the Arabidopsis pathogenesis-related (PR)-genes including AtPR-1, AtPR-4 and AtPR-5. CASAR82A overexpression enhanced the resistance against infections by Pseudomonas syringae pv. tomato, Fusarium oxysporum f.sp. matthiolae or Botrytis cinerea. The transgenic plants also exhibited increased NaCl and drought tolerance during all growth stages. Moreover, the methyl viologen test showed that the transgenic plants were tolerant to oxidative stress. The purified recombinant CASAR82A protein and crude protein extracts of the transgenic plants exhibited antifungal activity against some phytopathogenic fungi, indicating that the enhanced resistance of the transgenic plants to fungal pathogen infection may be due to the antifungal effect of SAR8.2 protein.
