Linear distance from the locus control region determines epsilon-globin transcriptional activity.
Article in Molecular and cellular biology, 2007. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
Enhancer elements modulate promoter activity over vast chromosomal distances, and mechanisms that ensure restrictive interactions between promoters and enhancers are critical for proper control of gene expression. The human beta-globin locus control region (LCR) activates expression of five genes in erythroid cells, including the proximal embryonic epsilon- and the distal adult beta-globin genes. To test for possible distance sensitivity of the genes to the LCR, we extended the distance between the LCR and genes by 2.3 kbp within the context of a yeast artificial chromosome, followed by the generation of transgenic mice (TgM). In these TgM lines, epsilon-globin gene expression decreased by 90%, while the more distantly located gamma- or beta-globin genes were not affected. Remarkably, introduction of a consensus EKLF binding site into the epsilon-globin promoter rendered its expression distance insensitive; when tested in an EKLF-null genetic background, expression of the mutant epsilon-globin gene was severely compromised. Thus, the epsilon-globin gene differs in its distance sensitivity to the LCR from the other beta-like globin genes, which is, at least in part, determined by the transcription factor EKLF.
