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
backgroundPrunus avium (L.) L. commonly known as sweet cherry, represents an economically significant tree species valued for its fruit production, rootstock potential, and timber quality. With an extensive domestication history spanning centuries, this species has given rise to numerous modern cultivars. Understanding the genomic variation and genetic diversity within P. avium cultivars is crucial for advancing breeding programs and optimizing resource utilization. While the nuclear genome of P. avium has been well characterized, the intraspecific variation of its plastome (plastid genome) remains largely unexplored. In this study, we conducted analyses of 110 plastomes representing 34 genetically distinct sweet cherry cultivars, including 98 newly assembled plastomes from varieties cultivated in China.
resultsThe complete plastomes ranged in size from 157,667 to 157,987 base pairs, with a consistent GC content of approximately 36.7%. Phylogenetic reconstruction, and principal component analysis (PCA) consistently identified three major lineages, two of which displayed remarkably low genetic diversity. Among the 110 P. avium accessions, we identified 11 distinct plastid haplotypes, with approximately 70% accessions sharing a common haplotype (Hap2). Comparative analysis demonstrated significantly reduced genetic diversity in modern cultivars compared to landraces and wild accessions, reflecting extensive clonal propagation in commercial breeding programs. Furthermore, we identified lineage-specific mutation hotspots and developed potential molecular markers for cultivar discrimination.
conclusionsThis study elucidates the evolutionary patterns and plastomic architectureof China's predominant cultivated sweet cherry varieties. These findings provide a critical bridge toward comprehensive cherry pan-plastome research while establishing foundational insights into the domestication history of this economically significant species.
