Construction and phenotypic analysis of mice carrying a duplication of the major histocompatibility class I (MHC-I) locus.

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
Copy number variation (CNV) has been associated increasingly with altered susceptibility to human disease. Large CNVs are likely to incur disease risk or resilience via predictable changes in gene dosage that are relatively straightforward to model using chromosomal engineering in mice. The classical class I major histocompatibility locus (MHC-I) contains a dense set of genes essential for innate immune system function in vertebrates. MHC-I genes are highly polymorphic and genetic variation in the region is associated with altered susceptibility to a wide variety of common diseases. Here we investigated the role of gene dosage within MHC-I on susceptibility to disease by engineering a mouse line carrying a 1.9-Mb duplication of this region [called Dp(MHC-I)]. Extensive phenotypic analysis of heterozygous (3N) Dp(MHC-I) animals did not reveal altered blood and stem cell parameters, susceptibility to high-fat diet, death by cancer, or contact dermatitis. However, several measures of disease severity in a model of atherosclerosis were improved, suggesting dosage-sensitive modulators of cardiovascular disease. Homozygous Dp(MHC-I)/Dp(MHC-I) mice demonstrated embryonic lethality. These mice serve as a model for studying the consequences of targeted gene dosage alteration in MHC-I with functional and evolutionary implications.
