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

Chicken antibodies are increasingly being used as diagnostic and therapeutic tools. As only the genomic organization of the micro encoding gene was previously known, we analysed the chicken immunoglobulin Y (IgY) and IgA (upsilon and alpha chain) immunoglobulin heavy-chain constant region (IGHC) genes and the organization of the chicken IGHC locus. The alpha gene is encoded by four separate exons, whereas, surprisingly, there is no intervening DNA sequence between the CH1 and CH2 domains of the IgY heavy chain, which is thus encoded by three exons separated by two introns. DNA sequence analysis shows that the exon boundaries of the chicken IGHC genes are not consistent with published domain borders. Furthermore, differences in DNA sequence confirm the existence of IgY, IgA and IgM allotypes in chickens. Finally, our results show that the IGHC genes of chicken (IgY, IgA and IgM) are all colocated on chromosome E18C15W15, where the alpha gene is located upstream of the upsilon gene in an inverted transcriptional orientation. The distances between the mu and alpha genes and the alpha and upsilon genes are about 18 and 15 kilobases, respectively, and thus, the size of the whole chicken IGHC locus is approximately 67 kilobases.
