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
key messageOsUGT72F1 enhances heat tolerance in plants by improving ROS scavenging and modifying multiple metabolic pathways, under the regulation of transcription factors OsHSFA3 and OsHSFA4a. High temperature is one of the most critical environmental constraints affecting plant growth and development, ultimately leading to yield losses in crops such as rice (Oryza sativa L.). UDP (uridine diphosphate)-dependent glycosyltransferases (UGTs) are believed to play crucial roles in coping with environmental stresses. However, the functions for the vast majority of UGTs under high temperature stress remain largely unknown. In this study, we isolated and characterized a high temperature responsive UDP-glycosyltransferase gene OsUGT72F1 in rice. Our findings demonstrated that overexpression of OsUGT72F1 enhanced heat-stress tolerance, while the mutant plants displayed a sensitive phenotype under the same stress conditions. Ectopic expression of OsUGT72F1 in Arabidopsis thaliana also conferred improved heat tolerance to the plants. Further investigation revealed that OsUGT72F1 reduced the generation of reactive oxygen species (ROS) and boosted the activity of antioxidant enzymes, thereby alleviating oxidative damage under heat-stress conditions. Moreover, transcriptomic analysis indicated that the action of OsUGT72F1 leads to the upregulation of multiple metabolic pathways including phenylpropanoid biosynthesis, zeatin biosynthesis, and flavonoid biosynthesis. In addition, the upstream regulatory mechanism of the OsUGT72F1 gene has been identified. We found that the transcription factors OsHSFA3 and OsHSFA4a can bind to the OsUGT72F1 promoter and enhance its transcription level. Together, this study revealed that the glycosyltransferase gene OsUGT72F1 plays a vital role in the adaptive adjustment of high temperature stress in plants, revealing a new heat tolerance pathway and providing a promising gene candidate for the breeding of heat-resistant crop varieties.
