Limited MHC class II gene polymorphism in the West African chimpanzee is distributed maximally by haplotype diversity.
Article in Immunogenetics, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 7 papers, 1 of them a synthesis that pooled it.
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
Chimpanzees have been used for some time as an animal model in research on immune-related diseases in humans. The major histocompatibility complex (MHC) region of the chimpanzee has also been the subject of studies in which the attention was mainly on the class I genes. Although full-length sequence information is available on the DRB region genes, such detailed information is lacking for the other class II genes and, if present, is based mainly on exon 2 sequences. In the present study, full-length sequencing was performed on DQ, DP, and DRA genes in a cohort of 67 pedigreed animals, thereby allowing a thorough analysis of the MHC class II repertoire. The results demonstrate that the number of MHC class II lineages and alleles is relatively low, whereas haplotype diversity (combination of genes/alleles on a chromosome) seems to have been maximised by crossing-over processes.
