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

Brassica rapa has been a key oilseed and vegetable crop since the Neolithic era, yet its obscure evolutionary history has hindered understanding of its domestication and the speciation of its allotetraploid descendants, Brassica napus and Brassica juncea. Here we defined pan-blocks comprising all syntenic regions from 21 B. rapa genome assemblies and analyzed 3,330 accessions spanning the three species to reconstruct the evolutionary trajectory of the Brassica A genome. Our findings reveal its origin in Central and West Asia and subsequent spread across Eurasia by means of three routes. An ancient inversion was identified that supports the divergent origins of the A subgenomes in B. napus and B. juncea. Furthermore, the S-locus exhibited exceptional haplotype diversity, with each variant characterized by a unique transposable element barcode pattern essential for the self-incompatibility system. These findings emphasize the significant value of pan-block-integrated 3,330 A genome variants for the Brassica research community.
