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, ubiquitously expressed molecules with a role in antigen presentation. Class I cDNA sequences have previously been reported that are thought to derive from putative nonclassical class I genes. We have located four nonclassical class I genes within the cattle genome; three are close to the MIC genes, and one is close to the classical class I genes. The genomic position relative to anchor genes is very similar to the arrangement reported in the pig MHC region. We have designed gene-specific oligonucleotide primers with which to investigate the presence of these genes in distinct and well-defined MHC haplotypes and to assess transcription in different cell types. Analysis and comparison of all sequences allows an assessment of allelic variation in each case. Partial characterisation gives an indication of the possible role and likely importance of each of these genes.
