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

backgroundCRISPR/Cas9 system is a powerful tool for knocking out genes in cells. However, genes essential for cell survival cannot be directly knocked out. Traditionally, generation of conditional knockout cells requires multiple steps.

resultsIn this study, we developed an easy and efficient strategy to generate conditional knockout cells by using double episomal vectors - one which expresses gRNA and Cas9 nuclease, and the other expresses an inducible rescue gene. Using this system which we named "krCRISPR" (knockout-rescue CRISPR), we showed that essential genes,

conclusionsThe krCRISPR system offers an easy and efficient platform that facilitates the study of essential genes' function.
