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 Cre/LoxP-based conditional knockout technology is a powerful tool for gene function analysis that allows region- and time-specific gene manipulation. However, inserting a pair of LoxP cassettes to generate conditional knockout can be technically challenging and thus time- and resource-consuming. This study proposes an efficient, low-cost method to generate floxed mice using in vitro fertilization and the CRISPR-Cas9 system over two consecutive generations. This method allowed us to produce floxed mice targeting exons 5 and 6 of CaMK1 in a short period of 125 days, using only 16 mice. In addition, we directly edited the genome of fertilized eggs of mice with our target genetic background, C57BL/6 N, to eliminate additional backcrossing steps. We confirmed that the genome of the generated floxed mice was responsive to the Cre protein. This low-cost, time-saving method for generating conditional knockout will facilitate comprehensive, tissue-specific genome analyses.
