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

backgroundTo meet the requirements of the rapidly progressing genetic testing technologies in clinical laboratories, assuring the quality of genetic tests by utilizing appropriate quality control materials is of paramount importance. The CRISPR/Cas9 technology was used to prepare quality control materials because genome-edited human cell lines are one of the major resources for quality control materials.

methodsIn this study, in vitro transcribed sgRNA were transfected into a Cas9-expressing lymphoblastoid cell line (LCL)-by electroporation-to simulate the SEA-type deletion observed in α-thalassemia. The edited positive cell line was screened and identified by polymerase chain reaction (PCR) followed by Sanger sequencing. The whole-genome sequencing was also performed to show evidence of predicted mutation.

resultsThe results showed that electroporation of the in vitro transcribed gRNAs into stable Cas9-expressing LCL was a more efficient gene-editing technique as compared to plasmid-mediated transfection, and that the positive rates could reach up to 35.9%. The predominance of indel sizes relative to the predicted deletion length was clustered between 10 and 0 bp. The results of whole-genome sequencing also demonstrated the existence of SEA-type deletion of α-thalassemia.

conclusionsGene-editing based on Cas9-expressing LCL by electroporation of sgRNA was a more efficient approach to introduce mutations for generating quality control materials for genetic testing. The edited lymphoblastoid cell lines were feasible to serve as quality control materials in genetic testing.
