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

Genotyping by targeting short tandem repeats (STRs) has been widely used in forensic applications. However, most commercial kits detect autosomal STRs or Y-STRs alone, which waste both time and opportunity. The AGCU Expressmarker 16 + 22Y Kit includes 16 autosomal and 22 Y-chromosomal STR loci and is designed for the forensic science field and obtaining quicker results. Here, we conducted the validation study according to Scientific Working Group on DNA Analysis Methods (SWGDAM) guidelines. Validation of PCR-based studies, species specificity, sensitivity, DNA mixture studies, inhibitors, precision, and sizing accuracy were performed. Furthermore, this system was also tested in 346 random male samples from Han, Hui, Tibetan, and Zhuang populations in China, showing its high power for forensic discrimination in the Chinese population. In addition, this system was able to deal with AMELY deletion cases, which can correctly identify sex in forensic criminal investigations. Our results suggested that the AGCU Expressmarker 16 + 22Y Kit is a useful tool for rapid criminal investigation.
