Identification and distribution of Puroindoline b-2 variant gene homologs in Hordeum.
Article in Genetica, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 barley hordoindoline genes (Hina and Hinb) are homologous to the wheat puroindoline genes (Pina and Pinb). These genes are involved in grain hardness, which is an important quality for barley processing. We identified novel variants of Hina and Hinb in 10 wild Hordeum species (H. bogdanii, H. brachyantherum, H. bulbosum, H. chilense, H. comosum, H. marinum, H. murinum, H. patagonicum, H. pusillum, and H. roshevitzii) covering all Hordeum genomes and preliminarily named them Hinc. These nucleotide sequences were highly similar to those of Puroindoline b-2 variant genes (Pinb-2v) and were located on chromosome 7I in H. chilense. The Hinc genes in H. bogdanii, H. bulbosum, H. patagonicum, and H. roshevitzii were pseudogenes possessing in-frame stop codons. We also found a partial Hinc sequence in H. murinum. This gene was not found in cultivated barley and H. vulgare subsp. spontaneum. The phylogenetic tree of Gsp-1, Hin, and Pin genes demonstrates that Hinc and Pinb-2v genes formed one cluster. Therefore, we considered that Hinc and Pinb-2v genes shared a common ancestral gene and were homologous to each other. We also studied the evolutional process of Gsp-1, Hin, and Pin genes. Our results suggested that Gsp-1 might be the most closely related to a putative ancestral gene on Ha locus.
