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
Introduction: Soil cadmium (Cd) contamination is considered to be one of the adverse stresses to which plants are subject. Research has demonstrated that exogenous calcium plays a crucial role in plant stress resistance. Methods: Here, a controlled comparative experiment was conducted using peanut seedlings ( Results: In the context of Cd stress, a marked inhibition in the growth parameters, photosynthetic activity, and root architecture of peanut seedlings was observed. This inhibition resulted in a significant accumulation of reactive oxygen species (ROS) within the plants. The application of exogenous calcium has been demonstrated to effectively alleviate Cd toxicity, with SCC exhibiting particularly notable efficacy in this regard. In comparison with Cd treatment, SCC significantly improved plant growth parameters and photosynthetic efficiency. Furthermore, SCC significantly enhanced superoxide dismutase (SOD) activity in tissues while concomitantly reducing malondialdehyde (MDA) and ROS levels, thereby mitigating membrane lipid oxidation. Concurrently, the analysis revealed that the SCC samples exhibited an upregulation of key genes, including AUX/IAA, GH3, SAUR, and JAZ. These genes have been implicated in promoting root growth and activating defence-related hormone pathways. Structural equation modelling further indicated that chlorophyll fluorescence exerted a significant positive influence on biomass accumulation, while excessive reactive oxygen species and osmotic regulators served as major inhibitory factors. Discussion: Consequently, SCC effectively mitigates Cd toxicity by stabilising photosynthetic systems, enhancing antioxidant defences, and regulating hormonal signalling, thereby promoting recovery of peanut seedling growth. The present study offers novel insights and a scientific basis for the efficient utilisation of Ca-containing fertilisers and the mitigation of heavy metal pollution in agricultural fields.
