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
MAIN
conclusionThrough multi-faceted comparative analysis of MITEs across six pear genomes, we revealed their distribution patterns, functional impacts and their significant role as genomic origins for miRNAs, with copy number being the most critical factor for MITE-miRNA transformation, providing valuable insights for future research. Miniature inverted-repeat transposable elements (MITEs) are prevalent in plant genomes and play a significant role in genome evolution and diversity. The availability of high-quality genome sequences for six pear species-Pyrus bretschneideri Rehd cv. 'Dangshan Suli', Pyrus communis L. cv. 'Bartlett', Pyrus pyrifolia Nakai cv. 'Nijisseiki' and 'Cuiguan', Pyrus ussuriensis maxim cv. 'Zhongai No.1', Pyrus betulifolia Bunge cv. 'Duli'-has facilitated the annotation and comparative analysis of MITEs in these species. Consequently, we identified 12,759 intact MITEs belonging to 750 families. Sequence diversity analysis revealed that these MITEs underwent one or two rounds of amplification burst events within the pear genomes. Among them, 10,368 intact MITEs demonstrated collinearity across six pear species. Further investigation indicated that MITEs are predominantly located upstream regions of genes. Notably, 1832 genes exhibited potential regulation (either up-regulation or down-regulation) due to MITE insertions. Additionally, 4421 previously missing genes, disrupted by MITE insertions, were restored and re-annotated. We identified 8855 MITE-miRNAs belonging to 370 families across all six species, with approximately 75% of miRNAs originating from MITEs. Machine learning analysis revealed copy number as the most influential feature for MITE-miRNA transformation, followed by MITE length and structure stability. These findings provide valuable insights into transposable elements' role in shaping genome diversity and their impact on functional genes and miRNA genesis within pear genomes.
