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
key messageWe physically dissected and mapped wheat chromosome 2B and its homoeologues in Aegilops speltoides and Thinopyrum elongatum based on meiotic homoeologous recombination, providing a unique physical framework for genome studies. Common wheat has a large and complex genome with narrow genetic diversity and various degrees of recombination between the A, B, and D subgenomes. This has limited the homologous recombination-based genome studies in wheat. Here, we exploited meiotic homoeologous recombination for molecular mapping of wheat chromosome 2B and its homoeologue 2S from Aegilops speltoides and 2E from Thinopyrum elongatum. The 2B-2S and 2B-2E recombination was induced by the ph1b mutant, and recovered using molecular markers and fluorescent genomic in situ hybridization (FGISH). A total of 112 2B-2S and 87 2B-2E recombinants involving different chromosome regions were developed and physically delineated by FGISH. The 2B-2S and 2B-2E recombination hotspots mapped to the subterminal regions on both arms. Recombination hotspots with the highest recombination rates mapped to the short arms. Eighty-three 2B-2S and 67 2B-2E recombinants were genotyped using the wheat 90 K SNP arrays. Based on the genotyping results and FGISH patterns of the recombinants, chromosomes 2B, 2S, and 2E were partitioned into 93, 66, and 46 bins, respectively. In total, 1037 SNPs physically mapped onto distinct bins of these three homoeologous chromosomes. A homoeologous recombination-based bin map was constructed for chromosome 2B, providing a unique physical framework for genome studies in wheat and its relatives. Meiotic homoeologous recombination also facilitates gene introgression to diversify the wheat genome for germplasm development. Therefore, homoeologous recombination-based studies enhance understanding of the wheat genome and its homoeologous counterparts from wild grasses, and expand the genetic variability of the wheat genome.
