Meiotic recombinations within major histocompatibility complex of human embryos.
Article in Immunogenetics, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
We studied the rate and pattern of recombinations within the extended major histocompatibility complex (MHC) locus of the human embryos obtained during preimplantation genetic diagnosis (PGD) for HLA compatibility. Recombinant allele frequency was on average 5.33 %, and recombination rate was 0.44 cM/Mb in the 12.2 Mb of the extended MHC locus. Recombination rate varied up to 14-fold (0.19-2.73 cM/Mb) between cases, and maternal recombination rate was on average 3.8 times higher than paternal alleles. More than 69 % of the recombination hot spots were clustered within the extended class II region where the recombination rate was 5.4 times more than that in extended class I region. These findings indicate the potential of PGD to study the mechanisms of linkage disequilibrium within MHC locus of human embryos, demonstrate the recombination characteristics within extended MHC loci of human embryos in comparison to sperm and family studies, and point to the significance of design and interpretation of PGD for HLA compatibility to avoid misdiagnosis because of meiotic recombinations.
