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
A previous study in wheat (Triticum aestivum L.) identified two candidate genes controlling a quantitative trait locus (QTL) for high-molecular-weight glutenin subunit (HMW-GS) GluBx. These candidates were Glu-B1-1, the structural gene coding for Glu1Bx, and the B homoeologous gene coding for SPA (spa-B), a seed storage protein activator. The goal of this study was to identify the best candidate gene for this QTL. Single nucleotide polymorphisms (SNPs) are an abundant source of DNA polymorphisms that have been successfully used to identify loci associated with particular phenotypes. As no linkage disequilibrium was detected between Glu-B1-1 and spa-B, we performed an association study to identify the individual gene responsible for the QTL. Six SNPs, three located in Glu-B1-1 and three in spa-B, were genotyped by mass spectrometry in a collection of 113 bread wheat lines. These lines were also evaluated for protein content as well as the total quantity of HMW-GSs and of each HMW-GS in seed samples from two harvest years. Significant associations were detected only between Glu-B1-1 polymorphism and most of the traits evaluated. Spa-B was unambiguously discarded as a candidate. To our knowledge, this is the first report on an association study that was successfully used to discriminate between two candidate genes.
