1 · What the graph read from it

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.

2 · The registry

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

Durum wheat (Triticum turgidum ssp. durum, 2n = 4x = 28, BBAA) is the second most cultivated lineage of wheat after hexaploid common wheat. Langdon is a prominent durum wheat cultivar, highly valued for its crucial role in the development of synthetic hexaploid wheat and its importance in agricultural research. Here, we present a high-quality chromosome-level genome assembly of Langdon using a combination of HiFi sequencing and high-throughput chromosome conformation capture (Hi-C) techniques. The total genome assembly size was 10.47 Gbp, with a benchmarking universal single-copy orthologs (BUSCO) score of 98.80%, consensus nucleotide quality value (QV) score of 50.31, long terminal repeat assembly index (LAI) value of 19.39, a scaffold N50 reached to 751.30 Mbp and a contig N50 value of 41.18 Mbp. Repetitive elements constituted 88.22% of the assembly, and 68,342 high confidence (HC) genes were annotated. The high-quality chromosome-level Langdon assembly can serve as a valuable reference for durum wheat, aiding gene research and comparative genomics, and leveraging synthetic hexaploid wheat's genetic resources to advance global wheat improvement.
