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

backgroundMost mutations in the COL6A3 gene lead to collagen VI-related myopathies. This is due to a reduced expression or mislocalization of the COL6A3 protein. Therefore, studying the consequence of knocking out the Col6a3 gene in mouse models is relevant, but the Col6a3 mouse models reported so far do not entirely abolish COL6A3 protein expression.

methodsHere, we present the development, validation and preliminary phenotypic characterization of a novel CRISPR-based knockout mouse model targeting Col6a3 exon 3 (Col6a3

resultsIn this mouse model, Col6a3 mRNA is still expressed at a similar level to wild-type littermates, although the expected protein is undetectable by mass spectrometry. Histological analysis of Col6a3

conclusionsIn summary, we performed the validation and preliminary phenotypic characterization of a novel Col6a3 knockout mouse model that could be further characterized and used to study COL6A3 biology and model collagen VI-associated diseases.
