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
Zinc deficiency in rice, a staple food consumed by more than half of the world's population, poses a major challenge to food safety and nutrition. In this study, the application of biosynthesized zinc oxide nanoparticles (ZnO NPs) was investigated as a sustainable strategy to solve this problem. The laboratory experiment on seed priming was conducted with four concentrations of ZnO nanoparticles (25, 50, 75 and 100 ppm) over three soaking times (12, 18 and 24 h). The priming of 25 ppm ZnO nanoparticles (NP) over a 24-hour period resulted in the highest germination and best growth of the rice seedlings, as evidenced by increased shoot and seedling length and improved overall seedling vigor. The optimized priming treatment (25 ppm ZnO NPs for 24 h), combined with a foliar spray of 100 ppm ZnO NPs applied at the panicle emergence and grain filling stage, was evaluated under field conditions for its effects on plant growth, yield and zinc content in rice. Field trials showed that this integrated approach significantly increased grain yield, straw yield and zinc accumulation in both the grains and straw compared to conventional methods. Biochemical analyzes showed an increase in chlorophyll content, total protein content and antioxidant enzyme activities (SOD, CAT and POX), all of which correlated with improved plant development. Phytohormone profiling showed increased levels of gibberellic acid (GA₃), indoleacetic acid (IAA) and salicylic acid (SA), which contributed to improved vegetative and reproductive performance. In addition, the expression of key zinc transporter genes (OsZIP1.1, OsZIP3, OsNAAT1 and OsYSL14) was significantly modulated in root and flag leaf tissue, indicating improved zinc uptake, translocation and accumulation in the grain. This study highlights the potential of biogenic ZnO NPs as a sustainable and cost-effective strategy for the biofortification of zinc in rice. It offers a novel solution to combat micronutrient deficiencies while improving plant productivity and nutritional quality.
