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
backgroundTartary buckwheat (Fagopyrum tataricum) is predominantly cultivated in arid and semi-arid mountainous regions. However, existing studies predominantly focus on describing the natural metabolic changes and the regulation of stress resistance during the germination of Tartary buckwheat. In contrast, research on the systematic influence of calcium ions on the germination physiology and metabolic networks of plants has yet to be reported. In this study, we elucidated the physiological mechanisms underlying calcium-mediated effects on Tartary buckwheat seed germination using six concentrations of CaCl₂ (0, 1, 2, 3, 4, and 5 g·L⁻¹).
resultsExogenous calcium application exhibited a concentration-dependent effect on seed germination, characterized by low-dose promotion and high-dose inhibition. An appropriate calcium supply significantly promoted the accumulation of osmoregulatory substances, including total sugars, reducing sugars, and free amino acids, by enhancing the decomposition of starch and soluble proteins. Furthermore, it facilitated the accumulation of active compounds, such as total phenols, flavonoids, and γ-aminobutyric acid, and enhanced the activities of key enzymes including phenylalanine ammonia-lyase, glutamate decarboxylase, and α-amylase, thereby improving seed antioxidant capacity. Metabolomic analysis revealed that linoleic acid metabolism, D-amino acid metabolism, and phenylalanine metabolism are the core pathways involved in calcium-regulated seed germination. Furthermore, exogenous calcium systematically improved stress resistance and germination capacity by modulating the levels of key metabolites in these pathways, thereby influencing lipid remodeling, nitrogen metabolism, and secondary metabolite synthesis.
conclusionsExogenous calcium effectively promoted the germination of Tartary buckwheat seeds by mediating amino acid and lipid metabolism, thus regulating osmotic balance and the antioxidant defense system. The optimal treatment concentration identified was 3 g·L⁻¹ CaCl₂. This study elucidates the multiple mechanisms through which calcium regulates the germination of Tartary buckwheat seeds at both physiological and metabolic levels, providing a theoretical basis and practical guidance for the rational application of calcium fertilizers in Tartary buckwheat cultivation.
