Molecular evidence for natural hybridization between Rumex crispus and R. obtusifolius (Polygonaceae) in Korea.
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 4 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
Interspecific hybridization has been suggested to occur frequently in Rumex (Polygonaceae). Several hypothesized combinations of parental species of hybrids based on their intermediate morphology have been suggested in the genus, but few of them have been phylogenetically tested. We analyzed nuclear and chloroplast DNA sequence data of a putative natural hybrid between Rumex crispus and Rumex obtusifolius from Korea to confirm its hybrid status and to determine the maternal parent. Analysis of the nuclear DNA pgiC region revealed that R. crispus and R. obtusifolius have contributed to the nuclear genome of the putative hybrids. The haplotype distribution pattern inferred from the combined sequence data set of five chloroplast DNA regions (matK, rbcL-accD IGS, trnK-rps16 IGS, ycf6-psbM IGS and psbA-trnH IGS) indicated bidirectional hybridization events between R. crispus and R. obtusifolius. This paper provides the first molecular evidence for interspecific hybridization between R. crispus and R. obtusifolius. In addition, our findings strongly suggested that Korean populations of Rumex japonicus have a hybrid origin, and R. crispus may represent one of the parental taxa.
