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 splotch (Sp) mouse mutant displays defects in neural tube closure in the form of exencephaly and spina bifida. Recently, mutations in the Pax-3 gene have been described in the radiation-induced Spr and Sp2H alleles. This led us to examine the integrity of the Pax-3 gene and its cellular mRNA transcript in the original, spontaneously arising Sp allele. A complex mutation in the Pax-3 gene including an A-->T transversion at the invariant 3' AG splice acceptor of intron 3 was identified in the Sp/Sp mutant. This genomic mutation abrogates the normal splicing of intron 3, resulting in the generation of four aberrantly spliced mRNA transcripts. Two of these Pax-3 transcripts make use of cryptic 3' splice sites within the downstream exon, generating small deletions which disrupt the reading frame of the transcripts. A third aberrant splicing event results in the deletion of exon 4, while a fourth retains intron 3. These aberrantly spliced mRNA transcripts are not expected to result in functional Pax-3 proteins and are thus responsible for the phenotype observed in the Sp mouse mutant.
