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 cattle major histocompatibility complex (MHC) region contains a variable number of classical class I genes encoding polymorphic molecules involved in antigen presentation. Six classical class I genes have been described, but assigning sequences to these genes has proved problematic. We propose a refinement of the existing nomenclature, which currently names the 97 known classical class I sequences in a single series. Phylogenetic analysis of the 3' portion of the coding region allows segregation of these into six groups; thus, we have prefixed existing names with the appropriate number. Although it is clear that some of these groups correspond to discrete genes, it is currently not possible to state definitively that all do. However, the main groupings are consistent, and in conjunction with other evidence, we feel it is now appropriate to rename the sequences accordingly. Segregation of sequences into groups in this way will facilitate ongoing research and future use of the cattle MHC section of the Immuno Polymorphism Database.
