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
This study explores the potential of a selenium containing elemental-based formulation (EBF) to reduce arsenic (As) stress in soil-grown rice, with an emphasis on its effects on grain trace element concentration, amino acid profiles, antioxidant enzyme activities, and gene expression. In addition to changes in amino acid content and stress-related gene expression, rice plants exposed to arsenic showed notable decreases in antioxidant enzyme activity (SOD, GPX, and CAT) and critical minerals (Fe, Zn, Mn, and Cu). Increased mineral recovery (29-37%), increased antioxidant enzyme activity (up to 32%), and modification of amino acid and gene expression patterns linked to stress reduction were all significantly improved by EBF supplementation. These results imply that by reestablishing the balance of minerals and nutrients, strengthening antioxidant defense systems, and controlling molecular reactions, EBF can successfully increase rice's resistance to arsenic poisoning. With important ramifications for food safety and crop management in arsenic-affected areas, this research offers a viable method for lowering arsenic buildup in rice grains and increasing crop output under polluted settings.
