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
To characterize the structure and expression of a large multigene family of α/β-gliadin genes, 90 individual α/β-gliadin genes harboring a promoter region were identified in the wheat cultivar Chinese Spring. These genes were classified into eleven groups by phylogenetic analysis, and the chromosomes they were derived from were determined. Of these genes, 50 had the basic α/β-gliadin domains and six conserved cysteine residues and 16, 16 and 18 of them were, respectively, located on chromosome 6A, 6B and 6D. Six genes had an additional cysteine residue, suggesting that these α/β-gliadins acquired the property of binding other proteins through intermolecular disulphide bands. Expression of α/β-gliadin genes in developing seeds was measured by quantitative RT-PCR using group-specific primers over 3 years. Expression patterns of these genes on the basis of accumulated temperature were similar among gene groups, whereas expression levels differed for the 3 years. The expression of most α/β-gliadin and other prolamin genes was correlated with the sunshine duration. On the other hand, although all α/β-gliadin genes had a common E-box within the -300 promoter region, some genes showed a particular expression pattern with respect to the sunshine duration, similarly to gene encoding high-molecular weight glutenin subunits and endosperm enzymes. These observations suggested that expression of each α/β-gliadin gene is differentially regulated by multiple regulatory factors.
