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 catch state in Mytilus anterior byssus retractor muscle is regulated by phosphorylation and dephosphorylation of twitchin, a member of the titin/connectin superfamily, and involves two serine residues, Ser-1075 (D1) and Ser-4316 (D2). This study was undertaken to examine whether isoforms of twitchin were expressed in various muscles of the mussel Mytilus galloprovincialis by reverse transcription-polymerase chain reaction. Mussel tissues, including both catch and non-catch muscles, contained various twitchin isoforms that all contained the D2 site and the kinase domain. However, sequence alterations were detected around the D1 site, notably a potential deletion of the D1 site. All isoforms from catch muscles contained both the D1 and D2 sites, whereas those from non-catch muscles also expressed the D2 site, but some of them lacked the D1 site. This suggests that the D1 site of twitchin is essential to the mechanism of catch. Genomic DNA analysis revealed that twitchin isoforms are produced by alternative splicing.
