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
MAIN
conclusionsALDH7B4 expression contributes to abiotic stress tolerance. The NAC transcription factor ATAF1 is a main regulator of expression of the ALDH7B4 gene in Arabidopsis thaliana as shown by ATAF1 mutants. The aldehyde dehydrogenase 7B4 (ALDH7B4) protein has important roles in detoxification of excessive aldehydes, elimination of reactive oxygen species (ROS) and inhibition of lipid peroxidation when plants are exposed to abiotic stress. However, the regulation of the expression of the ALDH7B4 gene under stress is largely unknown. Promoter studies revealed crucial cis-elements in the ALDH7B4 promoter in response to heat and stress combinations. Using a yeast one-hybrid assay, several NAC transcription factors, including ATAF1 were isolated. These transcription factors play an important role in plant adaptation to abiotic stress. ATAF1 activates the expression of the ALDH7B4 gene by directly binding to the promoter. Overexpression of ATAF1 in Arabidopsis plants results in elevated expression of ALDH7B4 in seeds, seedlings, and mature plants, whereas ATAF1 knock-out mutant plants abolished the expression of ALDH7B4. This study implies that ATAF1 may confer stress tolerance by up-regulating the target gene ALDH7B4.
