1 · What the graph read from it

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.

2 · The registry

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 synergistic effect of caffeic, jasmonic and salicylic acids and abscisic acid was highly effective in reducing the phytotoxic effect of Ni in isabgol plants by promoting growth, physiological processes and nutrient metabolism. This study was necessitated by the need to formulate an effective plan to make plants more tolerant to heavy metal-contaminated soil. The experiment was performed in a pot test using a completely randomized design with four replications. Nickel stress (100 mg/kg soil) significantly reduced root length (49.49%), shoot length (44.59%), root fresh weight (60.05%), shoot fresh weight (55.85%) and chlorophyll content (52.66%) compared to the unstressed control. The synergistic application of caffeic acid (1 mM), jasmonic acid (100 µM), salicylic acid (1 mM) and abscisic acid (50 µM) significantly mitigated these effects, increasing root length, shoot length by 21%1%, root fresh weight by 97%7% and shoot fresh weight by 59%9%, 21%1%, 97%7% and 45.31%, respectively, relative to the Ni-stressed control. This treatment also enhanced the activities of antioxidant enzymes, including superoxide dismutase (31.98%), peroxidase (46.24%), catalase (35.98%), ascorbate peroxidase (73.39%), glutathione peroxidase (62.94%) and glutathione reductase (64.76%), as well as non-enzymatic antioxidants such as ascorbic acid (48.57%), anthocyanins (64.40%), β-cyanin (27.83%), β-xanthin (42.13%), phenolic content (33.51%) and flavonoid content (38.70%). It also reduced Ni accumulation in roots, shoots and seeds by 33.72%, 36.31% and 49.69%, respectively, while improving the uptake of essential nutrients, such as Fe (30.66%), Mn (35.52%), Zn (32.98%) and N (14.99%). Photosynthetic efficiency, membrane stability and relative water content were also restored, leading to a 51.16% increase in seed yield. The synergistic interaction of these compounds enhances stress signaling, redox balance and metabolic regulation more effectively than their individual applications. Therefore, the combined exogenous application of caffeic acid, jasmonic acid, salicylic and abscisic acid is recommended as a sustainable strategy to improve Isabgol production in nickel-contaminated environments.
