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
Dwarf and high-density cultivation is a major trend in the apple industry, yet the regulatory mechanisms remain largely unexplored. In this study, we identified MdKNOX15, a KNOX transcription factor highly expressed in spur-type and dwarfing rootstock varieties, as a critical regulator of plant height. Overexpression of MdKNOX15 caused a gibberellin (GA)-deficient dwarf phenotype, whereas VIGS-mediated knockdown increased endogenous GA content and plant height. Exogenous GA alleviated, and uniconazole exacerbated, the dwarfism. Using DAP-seq and RNA-seq, we identified MdGA2ox7 and MdGA20ox2 as direct target genes. MdKNOX15 activated MdGA2ox7 and repressed MdGA20ox2 by binding to (T)TGAC elements in their promoters. Functional assays confirmed that MdGA2ox7 negatively, and MdGA20ox2 positively, regulates apple height. Furthermore, the DELLA homolog MdSLR1b physically interacted with MdKNOX15. Overexpression of MdSLR1b reduced plant height, while its knockdown alleviated the dwarfism induced by MdKNOX15 overexpression. MdKNOX15 enhanced MdSLR1b protein stability, especially under GA treatment, and MdSLR1b amplified the transcriptional regulation of downstream genes by MdKNOX15. Collectively, we propose a molecular model in which the MdKNOX15-MdSLR1b-MdGA2ox7/MdGA20ox2 module governs apple plant height, providing a theoretical basis for breeding dwarf apple varieties.
