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
BACKGROUND/
objectivesSoil salinization and alkalization critically limit global agricultural production. This study aimed to investigate the differential response mechanisms of rapeseed (
methodsSeedlings of a salt-tolerant variety, Huayouza 62 (H62), and a non-salt-tolerant variety, Xiangyou 15 (X15), were exposed to saline (NaCl:Na
results(1) H62 maintained favorable photosynthetic and carbon-nitrogen homeostasis. Notably, under saline and alkaline stresses, the activity of glutamate dehydrogenase (GDH) in H62 showed a significant increasing trend, whereas it was inhibited in X15. (2) Alkaline stress triggered more differential genes than saline stress, with H62 exhibiting broader transcriptional up-regulation in carbon-nitrogen metabolism. (3) Metabolomic profiling showed that H62 accumulated more beneficial metabolites than X15 under both stresses, such as phenolic acids, amino acids, and their derivatives. (4) In multi-omics analysis, key genes in starch-sucrose and amino acid metabolism in H62 were up-regulated to accumulate osmolytes, enabling an efficient defense network. However, X15's responses were disordered.
conclusionsH62 leverages robust transcriptional reprogramming to coordinate carbon-nitrogen metabolism, constituting a multidimensional defense network. This study provides potential physiological indicators, candidate genes, and metabolite markers associated with short-term saline-alkaline stress responses, laying a foundation for further exploration of stress response mechanisms.
