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
backgroundMonoglyceride lipase (MAGL) catalyzes the final step of triacylglycerol (TAG) hydrolysis, converting monoacylglycerol (MAG) into glycerol and free fatty acids. Although MAGL is critical for TAG metabolism, its physiological roles in plants remain poorly understood, compared to its functions in mammals.
resultsEighteen GmMAGL genes were identified from the genome of soybean (Glycine max), a major food and oil crop worldwide, with them being classified into 8 distinct subfamilies. Collinearity analysis indicated that segmental duplication was the only force driving GmMAGL gene family expansion. Multiple sequence alignment demonstrated that all 18 GmMAGLs harbored two typical structural features: the lipase GXSXG (Gly-X-Ser-X-Gly) motif and the catalytic triad consisting of Ser, Asp and His residues. Notably, GmMAGL14 and GmMAGL15 harbored an additional acyltransferase motif, distinguishing them as the only two bifunctional enzymes (hydrolase and acyltransferase) within the GmMAGL family. Additionally, multiple cis-elements associated with development, hormone, and stress response were identified in the promoter regions of GmMAGL genes. RNA-seq data revealed that GmMAGL genes displayed tissue-specific or distinct expression patterns in response to abiotic stresses and hormone treatments. Remarkably, the expression of GmMAGL10 and 14 was negatively related to oil accumulation during seed development while GmMAGL3 exhibited high expressions during seed germination. Particularly, 6 GmMAGL genes (GmMAGL1/3/4/6/8/12) showed significant modulation in response to drought stress in roots and leaves of soybean seedlings.
conclusionsThis study represents the first comprehensive identification of 18 members of GmMAGL gene family in soybean. GmMAGL10 and 14 may impact seed oil content negatively while GmMAGL3 function importantly in seed germination. GmMAGL1/3/4/6/8/12 might confer drought tolerance by activating lipid metabolism in soybean seedlings. The present data establish a foundation for further elucidation of the biological functions of GmMAGL genes and provide valuable target genes for genetic improvement in soybean and other crops.
