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

Rye (Secale cereale L.) is an important cereal crop known for its high yield potential and tolerance to biotic and abiotic stresses. However, its large, repeat-rich, and heterozygous genome has posed challenges for assembly compared to related species such as wheat and barley. Here, we present a high-quality, chromosome-scale genome assembly of the inbred line Lo7, generated using PacBio HiFi, Oxford Nanopore, Hi-C, and BioNano technologies with the TRITEX pipeline. The resulting Lo7_V3 assembly spans 6.76 Gb with a contig N50 of 128 Mb, correcting previous misorientations and fully assembling all seven centromeres. Repetitive clusters containing rye-specific satellite sequences (pSc200 and pSc250) are contiguously assembled. Their chromosomal positions are validated using FISH. Centromeric retrotransposon analysis reveals RLG_Abia and RLG_Abigail as abundant, recently active elements, unlike in wheat. Collectively, the Lo7_V3 genome assembly provides an improved genomic resource for future genomic research in rye and related cereal species.
