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
Salt stress (SS) significantly limits the productivity of fruit trees, highlighting the need for effective strategies to increase plant resistance. This study aimed to investigate the effects of ascorbic acid (AA) and SS on two grapevine rootstocks, 140Ruggeri (Ru) and 1103Paulsen (Pa), as well as two cultivars, Yaghouti (Ya) and Sultana (Su) The experiment was conducted in pots using three salinity levels (0 mM as control, 25 mM, and 50 mM NaCl) and four concentrations of AA (0 mM as distilled water, 2 mM, 4 mM, and 6 mM). In this study, we evaluated traits related to roots, shoots and leaves, photosynthetic pigments, leaf relative water content (RWC), electrolyte leakage (EL) and compatible osmolytes include total soluble carbohydrates, proline, and glycine betaine. The results indicated that the response of rootstocks and cultivars under SS varied according to stem, root, and leaf traits. The rootstocks Pa and Ru showing the least reduction in morphological traits and photosynthetic pigments and the highest synthesis of compatible osmolytes under SS. In contrast, the Su cultivars was identified as the most sensitive to SS, showing the strongest reduction in RWC, pigments, and osmolyte synthesis. The application of AA effectively alleviated SS, depending on rootstock and cultivar responses. In the rootstocks Pa and Ru, particularly at a concentration of 6 mM AA, was more pronounced in the synthesis of compatible osmolytes. Meanwhile, in the Su, the impact of this treatment was more significant in improving morphological traits and reducing EL under SS. Moreover, multivariate analyses clearly revealed the differentiation of rootstock and cultivar under SS and AA treatment. The findings of this study suggest that foliar application of AA can serve as a promising strategy to alleviate the detrimental effects of SS in grapevine.
