1 · What the graph read from 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.

2 · The registry

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 major histocompatibility complex (Mhc) consists of class I and class II genes. In the human Mhc (HLA) class II genes, nine DRB loci have been identified. To elucidate the origin of these duplicated loci and allelic divergences at the most polymorphic DRB1 locus, introns 4 and 5 as well as the 3' untranslated region (altogether approximately 1,000 base pairs) of seven HLA-DRB loci, three HLA-DRB1 alleles, and nine nonhuman primate DRB genes were examined. It is shown that there were two major diversification events in HLA-DRB genes, each involving gene duplications and allelic divergences. Approximately 50 million years (my) ago, DRB1*04 and an ancestor of the DRB1*03 cluster (DRB1*03, DRB1*15, and DRB3) diverged from each other and DRB5, DRB7, DRB8, and an ancestor of the DRB2 cluster (DRB2, DRB4, and DRB6) arose by gene duplication. Later, about 25 my ago, DRB1*15 diverged from DRB1*03, and DRB3 was duplicated from DRB1*03. Then, some 20 my ago, the lineage leading to the DRB2 cluster produced two new loci, DRB4 and DRB6. The DRB1*03 and DRB1*04 allelic lineages are extraordinarily old and have persisted longer than some duplicated genes. The orthologous relationships of DRB genes between human and Old World monkeys are apparent, but those between Catarrhini and New World monkeys are equivocal because of a rather rapid expansion and contraction of primate DRB genes by duplication and deletion.
