Epigenetic Protection of Vertebrate Lymphoid Progenitor Cells by Dnmt1.
Article in iScience, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
DNA methylation is a universal epigenetic mechanism involved in regulation of gene expression and genome stability. The DNA maintenance methylase DNMT1 ensures that DNA methylation patterns are faithfully transmitted to daughter cells during cell division. Because loss of DNMT1 is lethal, a pan-organismic analysis of DNMT1 function is lacking. We identified new recessive dnmt1 alleles in medaka and zebrafish and, guided by the structures of mutant proteins, generated a recessive variant of mouse Dnmt1. Each of the three missense mutations studied here distorts the catalytic pocket and reduces enzymatic activity. Because all three DNMT1 mutant animals are viable, it was possible to examine their phenotypes throughout life. The consequences of genome-wide hypomethylation of DNA of somatic tissues in the Dnmt1 mutants are surprisingly mild but consistently affect the development of the lymphoid lineage. Our findings indicate that developing lymphocytes in vertebrates are sensitive to perturbations of DNA maintenance methylation.
