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
This study explored the genetic constitutions of wheat-Agropyron cristatum 6P chromosomal translocation and determined the effects of 6P intercalary chromosome segment on thousand-grain weight and spike length in wheat. Crop wild relatives provide rich genetic resources for wheat improvement. Introduction of alien genes from Agropyron cristatum into common wheat can broaden its genetic diversity. In this study, radiation-induced wheat-A. cristatum translocation line Pubing3035 derived from the offspring of wheat-A. cristatum 6P chromosomes addition line was identified and analyzed using genomic in situ hybridization (GISH), dual-color fluorescence in situ hybridization (FISH), and molecular markers. GISH analysis revealed that Pubing3035 was a Ti1AS-6PL-1AS·1AL intercalary translocation. The breakpoint was pinpointed to locate near the centromeric region on the short arm of wheat chromosome 1A based on a constructed F2 linkage map and it was flanked by markers SSR12 and SSR263. The genotypic data, combined with the phenotypes, indicated that A. cristatum 6P chromosomal segment played an important role in regulating the thousand-grain weight and spike length. On average, the thousand-grain weight and spike length in translocation individuals were approximately 2.5 g higher and 0.7 cm longer than those in non-translocation individuals in F2 and BC1F1 populations. The clusters of quantitative trait loci for thousand-grain weight, spike length, and spikelet density contributed by 6P chromosome segment were mapped between A. cristatum unique marker Agc7155 and wheat marker SSR263, which, respectively, explained phenotypic variance of 24.96, 12.38 and 17.20 % with an LOD of 10.63, 4.89 and 5.59. Overall, the translocation Pubing3035 had a positive effect on the yield of wheat, which laid the foundation for the localization of A. cristatum excellent genes and made itself a promising and valuable germplasm for wheat improvement.
