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

This protocol presents an efficient genetic strategy to investigate gene function in the fungus Aspergillus niger. We combined 5S rRNA-CRISPR-Cas9 technology with Tet-on gene switch to generate conditional-expression mutants via precisely replacing native promoter with inducible promoter. We describe the design and DNA preparation for sgRNAs and donor DNA. We then detail the steps for DNA co-transformation into A. niger protoplasts by PEG-mediated transformation, followed by homozygote isolation. Finally, we describe the genome verification and strain validation of the isolates. For complete details on the use and execution of this protocol, please refer to Zheng et al. (2019).
