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
backgroundThe BZR family genes encode plant-specific transcription factors as pivotal regulators of plant BR signaling pathways, critically influencing plant growth and development.
resultsIn this study, we performed a genome-wide investigation of the BZR family gene in gerbera to identify the key components of the BR pathway that may function in petal growth. The identified BZR genes, named GhBEH1-7 (GhBEH1, GhBEH2, GhBEH3, GhBEH4, GhBEH5, GhBEH6, GhBEH7), are distributed across chromosomes 3, 5, 10, 11, 12, 14 and 15. These genes exhibit similar exon-intron structures and possess typical BZR family structures. Phylogenetic analysis clustered these genes into two distinct subgroups. Analysis of cis-acting elements revealed their involvement in hormone response, stress response, and growth regulation. Subcellular localization analysis indicated nuclear localization for GhBEH1 and GhBEH2, while the remaining five genes exhibited dual localization in the nucleus and cytoplasm. The transactivation assay indicated that GhBEH1 and GhBEH2 may function as transcriptional repressors, contrasting with the transcriptional activation observed for the other five genes. Notably, seven GhBEHs exhibit various expression patterns under different growth stages of ray florets and BR treatment conditions. Meanwhile GhBEH1 and GhBEH2 showed pronounced responsiveness to BR stimulation.
conclusionOur work explains genome-wide identification, characterization, and expression analysis of gerbera's BZR transcription factor family. We hinted that these seven GhBEHs are involved in petal growth and development regulation. These findings provide a basis for further studies on the biological function of the BZR gene family in petal growth and a theoretical basis for future horticultural application in gerbera.
