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
Seeds germination and seedlings growth are crucial factors in ensuring effective rice grain productivity. However, the mechanisms for maintaining seed vigor remains largely unknown. The seed aging phenomenon that occurs during storage poses a significant challenge to crop production, as it can lead to reduced germination rates and impaired seed vitality. The current study explored the underlying mechanisms that enable rice seeds to maintain high germination rates and seedling vigor after long - term storage. We employed transcriptomic and metabolomic techniques to identify metabolic changes and key genes associated with the aging of rice seeds during long - term storage. We utilized indicators such as imbibition rate (IR), germination rate (GR), mean germination time (MGT), germination coefficient (GC), germination index (GI), and germination potential (GP) to comprehensively assess germination activity. Traits including seedling emergence rate, seedling strength index, photosynthetic parameters, carbohydrate accumulation, and enzyme activity related to carbon metabolism were used to determine the impact of seed storage duration on seedling growth. Our research findings revealed significant differences in gene expression patterns and metabolic characteristics among seeds stored for different duration. Notably, IAA levels, the IAA/ABA ratio, and linoleic acid metabolism were identified as key factors affecting germination and seedling development. Results indicated that with the extension of storage duration, the germination potential and seedling development significantly declined. Current study provided a comprehensive understanding of the physiological and molecular mechanisms behind the germination and morphogenesis of rice seeds under different storage years. The insights gained from this study could be utilized to improve the storage and quality control of rice seeds, thereby ultimately enhancing agricultural productivity.
