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 messageA new wheat-Thinopyrum ponticum translocation line with excellent powdery mildew resistance was produced, and alien-specific PCR markers and FISH probes were developed by SLAF-seq. Powdery mildew is one of the most threatening diseases in wheat production. Thinopyrum ponticum (Podp.) Barkworth and D. R. Dewey, as a wild relative, has been used for wheat genetic improvement for the better part of a century. In view of the good powdery mildew resistance of Th. ponticum, we have been working to transfer the resistance genes from Th. ponticum to wheat by creating translocation lines. In this study, a new wheat-Th. ponticum translocation line with excellent resistance and agronomic performance was developed and through seedling disease evaluation, gene postulation and diagnostic marker analysis proved to carry a novel Pm gene derived from Th. ponticum. Cytogenetic analysis revealed that a small alien segment was translocated to the terminal of chromosome 1D to form new translocation TTh-1DS·1DL chromosome. The translocation breakpoint was determined to lie in 21.5 Mb region of chromosome 1D by using Wheat660K SNP array analysis. Based on specific-locus amplified fragment sequencing (SLAF-seq) technology, eight molecular markers and one repetitive sequence probe were developed, which were specific for Th. ponticum. Fortunately, the probe could be used in distinguishing six alien chromosome pairs in partial amphiploid Xiaoyan 7430 by fluorescence in situ hybridization (FISH). Furthermore, a Thinopyrum-specific oligonucleotide probe was designed depending on the sequence information of the FISH probe. The novel translocation line could be used in wheat disease resistance breeding, and these specific markers and probes will enable wheat breeders to rapidly trace the alien genome with the novel Pm gene(s).
