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
Tartary buckwheat (Fagopyrum tataricum) is an important crop used for edible food and medicinal usage. Drought annually brings reduction in crop yield and quality, causing enormous economic losses. Transcription factors are often involved in the regulation of plant responses to environmental stresses. In this study, we identified 233 MYB transcription factors in tartary buckwheat and classified them into 13 groups, including 1R, R2R3, 3R, 4R types. Gene structure and conserved motifs of these 233 FtMYBs suggested the relative conservation of these FtMYBs within each group. There is strong collinearity within the genomes of F. tataricum, with identifying syntenic gene pairs of FtMYB. Further, the expansion of FtMYB genes was attributed to whole genome duplication. The enrichment analysis of cis-acting elements in the FtMYB genes indicated that FtMYBs may participate in abiotic stress responses. The transcriptional changes of FtMYB genes in tartary buckwheat were then investigated using public data and qPCR. A number of FtMYB genes exhibited apparent transcript levels in the detected tissues and most of them disturbed their expression after the treatment of PEG6000 or natural treatment of tartary buckwheat seedlings. Some of the FtMYB genes showed a similar expression trend with qPCR validation. FtMYB gene FtPinG0005108900.01 were shown to activated by PEG6000 and natural drought treatment, and its encoded protein localizes to nucleus, revealing it as a typical transcription factor. Overexpression of FtPinG0005108900.01 increase the drought tolerance, and transcriptome analysis indicated that lignin synthesis other than flavonoid biosynthesis pathway was activated in the overexpressing plants following drought treatment. Our results provided detailed evolution and comparative genomic information of FtMYBs in tartary buckwheat and dissected the function of a FtMYB gene FtPinG0005108900.01 in response to drought.
