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
backgroundFruit size is a crucial agronomic trait that significantly influences fruit quality and economic value. Gibberellin serves as an effective phytohormone that promotes fruit expansion and is widely utilized during the early stages of fruit development. However, the mechanisms underlying GA-mediated fruit enlargement in pear, along with the associated genes and regulatory mechanisms, remain poorly understood.
resultsIn this study, pear cultivar 'Cuiguan' was treated with various combinations of GAs, specifically GA3, GA4 + 7, and GA3 + 4 + 7 at 30 days after flowering. The combination of GA3 + 4 + 7 produced the most pronounced increase in pear fruit size, primarily through promoting elongation. Anatomical analysis revealed that this treatment enhanced both cell proliferation and expansion. RNA-seq was conducted and identified differentially expressed genes associated with GA3 + 4 + 7-mediated fruit enlargement. Functional annotation and enrichment analyses highlighted the involvement of genes related to plant hormone signaling, cell growth, cell division, cell cycle, and transcription factors. Nine DEGs associated with fruit size were validated by RT-qPCR analysis, confirming the RNA-seq results.
conclusionsThis study elucidates the molecular mechanisms by which gibberellins regulate pear fruit development and identify key genes involved in this process, providing a foundation for future research on GA3 + 4 + 7-mediated fruit size regulation.
