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
The hetero-chitooligosaccharide (HTCOS) is a naturally occurring biopolymer in the exoskeleton of crustaceans and insects. Although some studies have been carried out on HTCOS in inducing plant resistance and promoting growth, the molecular mechanism of HTCOS in plants is not clear. In this study, an integrated analysis of metabolomics and transcriptomics was performed to analyze the response of Brassica napus to hetero-chitooligosaccharides treatment. The levels of 26 metabolites in B. napus were significantly changed under the HTCOS treatment. Amongst these metabolites, 9 metabolites were significantly up-regulated, including pentonic acid, indole-3-acetate, and γ-aminobutyric acid. Transcriptome data showed that there were 817 significantly up-regulated genes and 1064 significantly down-regulated genes in B. napus under the HTCOS treatment. Interestingly, the indole-3-acetate (IAA) content under the HTCOS treatment was about five times higher than that under the control condition. Moreover, four genes related to plant hormone signal transduction, three AUX/IAA genes, and one ARF gene, were significantly up-regulated under the HTCOS treatment. Furthermore, the plant height, branching number, and biomass of B. napus under the HTCOS treatment were significantly increased compared to that in the control condition. This evidence indicated that the HTCOS treatment contributed to accumulating the content of plant hormone IAA in the B. napus, up-regulating the expression of key genes in the signaling pathway of plant growth and improving the agronomic traits of B. napus.
