Exploring the ancestry and admixture of Mexican Oaxaca Mestizos from Southeast Mexico using next-generation sequencing of 11 HLA loci.
Review in Human immunology, 2019. 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
The Mestizos of Oaxaca resulted from the admixture of Zapotecan Natives with Spaniards and Africans. We selected 112 donors from Oaxaca and applied next-generation sequencing to characterize exon and intron variants in complete or extended HLA genes. Some alleles found, are unique to Mexican Natives and most likely will be absent in most major ethnicities, namely: Caucasians, Africans or Asians. Among these are HLA-A*68:03:01, HLA-A*68:05:01, HLA-C*03:04:01:02, HLA-C*15:09, HLA-C*3:05, HLA-C*03:06:01, HLA-B*39:05:01, HLA-B*35:14:01, HLA-B*35:12:01, HLA-B*35:43:01, HLA-B*40:05, HLA-B:40:08, HLA-B*51:02:01, HLA-B*35:24:01 and HLA-B*39:08. HLA-DQA1*05:05:01:05 and some HLA-DRB1 alleles were only present in Amerindians/Mestizos. Three haplotypes are unique to Mexican Natives, five to Middle-Eastern and Sephardi-Jews. We detected a novel HLA-DQA1*04:01:01 exon 4 variant. Any novel allele may have been positively selected to enlarge the peptide-binding repertoire, and some, like HLA-B*39:02:02 and HLA-B*39:05:01 were found with unique haplotype associations, suggesting convergent evolution events and/or allele lineage diversification. The allele frequencies were fairly evenly distributed in most HLA loci with the exception of HLA-DPB1. The application of NGS in Oaxaca is novel and will lead to better use in the clinical setting. It offers deep knowledge on the population structure, origins, migration, and discovery of new alleles and haplotypes that other techniques did not achieve.
