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

Limb-girdle muscular dystrophy type 2A (LGMD2A) is an autosomal recessive disorder caused by mutations in the CAPN3 gene. Its definitive diagnosis is laborious, since the clinical phenotype is often similar to other types of muscular dystrophy and since the CAPN3 gene encompasses a large genomic region with more than 300 pathogenic mutations described to date. In fact, it is estimated that nearly 25% of the cases with a phenotype suggestive of LGMD2A do not have mutations in the CAPN3 gene and that, in up to 22% of the cases, only one mutation is identified. In the present work, we have characterised CAPN3 messenger RNA (mRNA) expression in peripheral blood, and we have performed a retrospective diagnostic study with 26 LGMD2A patients, sequencing a transcript of CAPN3 present in white blood cells (WBCs). The 25% of the mutations presented in this paper (7/28) act modifying pre-mRNA splicing of the CAPN3 transcript, including the first deep-intronic mutation described to date in the CAPN3 gene. Our results determine that the sequencing of CAPN3 transcripts present in WBCs could be applied as a new approach for LGMD2A diagnosis. This method improves and simplifies diagnosis, since it combines the advantages of mRNA analysis in a more accessible and rapidly regenerated tissue. However, the lack of exon 15 in the CAPN3 isoforms present in blood, and the presence of mRNA degradation make it necessary to combine mRNA and DNA analyses in some specific cases.
