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 mouse genome contains four functional JH genes, which encode immunoglobulin heavy chain joining segments. The JH gene cluster is located a few kilobases 5' from the constant region genes (C genes) on chromosome 12. The polymerase chain reaction (PCR)-technique was used to amplify DNA stretches from mouse genome of approximately 1,340 nucleotides in length containing all four JH genes (Igh-J locus). PCR products were directly used as templates in Sanger's dideoxy-sequencing, and sequences were determined. Twelve inbred mouse strains belonging to ten different Igh-C haplotypes were studied. The strains were: BALB/c, C58/J, RIII, DBA/2, CE, RF, CBA, NZB/J, AKR, C57BL/10, SJL, and A/J. Five allelic forms of the Igh-J locus were found among these strains. The A/J mouse has an allele (e) which differs from the BALB/c allele (a) by 15 nucleotides. C57BL and SJL have the allele (b) with eight differences from BALB/c. The CBA allele (j) has two differences, and the CE allele (f) has a single nucleotide difference compared with the BALB/c sequence. Based on the JH, variable (V) and constant (C) region sequences we conclude that independent reshuffling of VH, JH, and CH gene clusters occurred during the evolution of Mus musculus.
