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
The Multiprotein Bridging Factor 1 (MBF1) gene family, a conserved transcriptional coactivator central to plant stress adaptation, has been systematically characterized in this study across diverse species, including the economically critical crop sugar beet (Beta vulgaris L.). Phylogenetic analysis delineated two evolutionarily distinct clades: Group I (MBF1a/b) with conserved exon-intron structures and Group II (MBF1c) exhibiting intron-poor architectures, a feature linked to rapid transcriptional activation under stress. In sugar beet, BvMBF1c demonstrated nuclear localization and pathogen-responsive expression dynamics, peaking within 48 h post-Cercospora beticola (C. beticola) inoculation. Yeast two-hybrid assays confirmed a novel interaction between BvMBF1c and trehalose-6-phosphate synthase (TPS5), implicating its role in osmotic regulation through trehalose biosynthesis—a mechanism critical for mitigating pathogen-induced cellular stress. Synteny and collinearity analyses revealed lineage-specific duplication events, underscoring the role of genomic plasticity in stress adaptation. Notably, MBF1c homologs displayed conserved microsynteny in woody perennials (Populus trichocarpa, Citrus sinensis) but diverged in monocots, reflecting adaptive evolution to species-specific environmental pressures. This study integrates evolutionary, structural, and functional insights to position MBF1c as a molecular hub bridging transcriptional regulation with metabolic homeostasis, offering actionable targets for breeding climate-resilient crops. Our findings highlight BvMBF1c as a candidate for enhancing disease resistance in sugar beet, with broader implications for improving stress tolerance in agronomically vital species.
