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 availability of a contig of bacterial artificial chromosome (BAC) clones spanning the equine major histocompatibility complex (MHC) made possible a detailed analysis of horse MHC class I genes. Prior to this study, only a single horse MHC class I gene had been sequenced at the genomic level. Although many ( approximately 60) MHC class I cDNA sequences had been determined and published, from this information, it was not possible to determine how many class I loci are expressed in horses or to assign individual sequences to allelic series. In this study, 15 MHC class I genes were identified in BAC subclones and fully sequenced. Because the BAC library donor horse had been bred for homozygosity at the MHC, these 15 genomic clones represent distinct MHC class I genes and pseudogenes and not alleles at a smaller number of loci. For five of the genes, cDNA sequences from these loci had previously been identified. Two additional expressed class I genes were discovered, bringing the known total of different equine MHC class I genes (loci) expressed as mRNA to seven. Expression of all seven loci was detected by reverse transcriptase-polymerase chain reaction in adult, fetal, and placental tissues. The remaining eight genes were designated as pseudogenes. This work resulted in moderate expansion of the horse MHC BAC contig length, and the remaining gap was shortened. The information contained in these equine MHC class I sequences will permit comparison of MHC class I genes expressed across different horse MHC haplotypes and between horses and other mammalian species.
