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
backgroundFlower color is a prominent ornamental characteristic in roses, and their petals contain a wide range of bioactive compounds. In this study, the petal development of the rose cultivar 'Juicy Terrazza' was categorized into three stages: tangerine-colored petals in the flower bud (JT-T), orange-colored petals of the blooming flower (JT-O), and pink-colored petals of the open flower (JT-P). We utilized transcriptomics and metabolomics approaches to investigate the genes and metabolites involved in the pigment metabolic pathway across all three stages of rose petals (JT-T, JT-O, and JT-P) for transcriptomics analysis and two stages (JT-T and JT-P) for metabolomics analysis.
resultA total of 872 metabolites were identified in rose flowers. Comparative analysis revealed significant differences in 153 accumulated metabolites between open flowers in JT-P and flower buds in JT-T. The flower coloration of this rose cultivar is primarily influenced by carotenoids and anthocyanins, with carotenoids being the main differential metabolites responsible for altering the flower colors during the transition from JT-T to JT-P, particularly β-carotene, violaxanthin and its derivatives. Furthermore, by conducting a comparative study on differentially expressed genes (DEGs) during the transition of petal color, potential candidate genes related to this specific phenotypic characteristic were successfully identified. PSY, PDS, ZISO, and ZDS genes showed significant down-regulation, while RcCCD4 exhibited strong up-regulation in JT-P compared with JT-T, which could directly contribute to the reduction of carotenoid contents during the JT-P stage. The TF-gene-metabolite correlations involved in the change of pigments in rose petals were identified through comprehensive data analysis. MYB308 and MYB1 (RchiOBHmChr3g0448721, RchiOBHmChr2g0116041) could play pivotal roles in the regulation of pigment metabolism in this rose cultivar.
conclusionsThese findings contribute to our understanding of the impact of specific metabolites and transcripts on flower color changes and the molecular mechanisms of carotenoid metabolism and flavonoid biosynthesis in rose flowers. The candidate key genes related to pigment metabolism may serve as valuable genetic resources for molecular breeding of ornamental plants with specific flower colors.
