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
backgroundArctium lappa L. (A. lappa), a plant of significant economic importance, is cultivated worldwide for its applications in food and medicine, presenting a compelling opportunity for genetic research within the Asteraceae family. Despite the importance of A. lappa genetic resources, the genome of the Peixian yellow A. lappa cultivar has not yet been sequenced.
resultsThis study presents a chromosome-level genome of the Peixian yellow A. lappa, the genome consists of a comprehensive 1.69 Gb reference and a scaffold N50 of 91.02 Mb. By utilizing Hi-C data, we anchored 99.12% of the assembled sequences onto 18 chromosomes and identified 40,665 protein-coding genes. The genome is predominantly composed of repetitive sequences, which constitute 68.32%, with long terminal repeats (LTRs) accounting for 65.66% of the total. A comparative genomic analysis with the Gansu A. lappa genome revealed significant genetic variations, including 2,972,809 single nucleotide polymorphisms (SNPs), 608,644 insertions/deletions (INDELs), and 11,800 structural variations (SVs). Furthermore, transcriptomic analyses comparing Peixian yellow A. lappa and Liu chuan li xiang A. lappa have shed light on the molecular mechanisms underlying carotenoid biosynthesis in Peixian yellow A. lappa. A total of 16 differentially expressed genes (DEGs) were specifically associated with the carotenoid biosynthesis pathway. Among these, several genes, including PSY1, PDS, BCH2, VDE, NCED1, and NCED2, were downregulated in Peixian yellow A. lappa. In contrast, other genes such as DXS, IDI1, CCD8B, CCS, and CCD4 were upregulated. Additionally, several transcription factors linked to carotenoid biosynthesis were identified, including MYC2, WRK35, and HY5. Most of these transcription factors were downregulated in Peixian yellow A. lappa, with the exception of Arcla.08g00830, which encodes MYC2.
conclusionThis high-quality genomic resource is poised to enhance genome-informed breeding strategies and improve A. lappa quality, offering valuable insights for breeding programs aimed at enhancing desirable traits in A. lappa.
