Genetic introgression between different groups reveals the differential process of Asian cultivated rice.
Article in Scientific reports, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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 Asian cultivated rice consists of two major subspecies: indica and japonica. There are already many reports about the existence of genetic introgression between the two subspecies. They propose some possible introgression-related genes from the comparison of population parameters. This study uses the genome-wide variation data of Asia cultivated rice to investigate their genetic introgression on the whole genome level. We detect a total of 13 significantly high introgression loci between the tropical japonica and indica populations. Two different methods are used to identify the genetic introgression regions. For most of the detected introgression regions, they generally get consistent results. Some previously known introgression genes are detected in the identified introgression loci, such as heat resistance gene TT1 and GLW7. The biological functions for these genetic introgression regions are annotated by the published QTL mapping results. We find that genetic introgression plays a vital role in the determination of both the phenotype and the domestication process of different groups. Our study also provides useful information and resources for the study of rice gene function and the domestication process.
