Whole-Genome Variants Resource of 144 Oryza rufipogon Accessions.
Article in Scientific data, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
The global food security crisis highlights the urgent need to improve rice yield and quality. Oryza rufipogon, the wild progenitor of cultivated rice, offers valuable genetic diversity, yet its genome remains underexplored. We conducted whole-genome resequencing (WGS) of 144 O. rufipogon accessions from 13 countries, generating ~400 GB of data using the Illumina NovaSeq 6000 platform. After quality control, 97.58% of reads aligned to the reference genome, achieving 87.97% coverage with 12.47× average depth. We identified a total of 6,183,832 SNPs and 748,493 InDels across 12 chromosomes. Chromosome 1 exhibited the most variants (715,636 SNPs and 91,276 InDels), while chromosome 9 had the fewest (384,000 SNPs and 44,817 InDels). Mutation rates were 67 SNPs and 559 InDels per million base pairs. Notably, 40.75% of SNPs and 46.09% of InDels were found upstream of genes, with 19.13% and 22.26% located downstream, respectively. A transition-to-transversion ratio (Ti/Tv) of 2.72 confirmed the data's reliability. Our findings offer a comprehensive genomic variation resource for O. rufipogon, supporting future genetic research and rice breeding efforts.
