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 stem, leaf and stripe rust resistance genes Sr31, Lr26 and Yr9, located on the short arm of rye chromosome 1, have been widely used in wheat by means of wheat-rye translocation chromosomes. Previous studies have suggested that these resistance specificities are encoded by either closely-linked genes, or by a single gene capable of recognizing all three rust species. To investigate these issues, two 1BL.1RS wheat lines, one with and one without Sr31, Lr26 and Yr9, were used as parents for a high-resolution F2 mapping family. Thirty-six recombinants were identified between two PCR markers 2.3 cM apart that flanked the resistance locus. In one recombinant, Lr26 was separated from Sr31 and Yr9. Mutation studies recovered mutants that separated all three rust resistance genes. Thus, together, the recombination and mutation studies suggest that Sr31, Lr26 and Yr9 are separate closely-linked genes. An additional 16 DNA markers were mapped in this region. Multiple RFLP markers, identified using part of the barley Mla powdery mildew resistance gene as probe, co-segregated with Sr31 and Yr9. One deletion mutant that had lost Sr31, Lr26 and Yr9 retained all Mla markers, suggesting that the family of genes on 1RS identified by the Mla probe does not contain the Sr31, Lr26 or Yr9 genes. The genetic stocks and DNA markers generated from this study should facilitate the future cloning of Sr31, Lr26 and Yr9.
