The HMGA gene family in chordates: evolutionary perspectives from amphioxus.
Article in Development genes and evolution, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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
High mobility group A proteins of vertebrates, HMGA1 and 2, are chromatin architectural factors involved in development, cell differentiation, and neoplastic transformation. Here, we characterize an amphioxus HMGA gene ortholog and analyze its expression. As a basal chordate, amphioxus is well placed to provide insights into the evolution of the HMGA gene family, particularly in the transition from invertebrates to vertebrates. Our phylogenetic analysis supports the basal position of amphioxus, echinoderm, and hemichordate HMGA sequences to those of vertebrate HMGA1 and HMGA2. Consistent with this, the genomic landscape around amphioxus HMGA shares features with both. Whole mount in situ hybridization shows that amphioxus HMGA mRNA is detectable from neurula stage onwards in both nervous and non-nervous tissues. This correlates with protein expression monitored immunocytochemically using antibodies against human HMGA2 protein, revealing especially high levels of expression in cells of the lamellar body, the amphioxus homolog of the pineal, suggesting that the gene may have, among its many functions, an evolutionarily conserved role in photoreceptor differentiation.
