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

Lettuce (Lactuca sativa L.) is among the most widely cultivated and consumed vegetables globally, valued for its phytonutrients beneficial for human health. Here, we report the high-quality reference super-pangenome for the Lactuca genus by integrating 12 chromosome-scale genomes from representative cultivated lettuce morphotypes, landrace, and wild relatives, and investigate lettuce genome evolution and domestication. These assemblies exhibit diverse genome sizes ranging from 2.1 Gb to 5.5 Gb with abundant repetitive sequences, and expansion of repetitive sequences, associated with low DNA methylation levels, likely contributes to the genome size variations. Furthermore, by constructing a graph-based lettuce pangenome reference, we explore the landscape, genomic, and epigenetic features of structural variations, and reveal their contributions to gene expression and domestication. We also identify copy number variations in FLOWERING LOCUS C in association with delayed flowering in cultivated lettuce. Overall, this comprehensive Lactuca super-pangenome assembly will expedite functional genomics studies and breeding efforts of this globally important crop.
