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

Short tandem repeats of the Y chromosome (Y-STRs) are powerful genetic markers for investigating paternity testing and widely used in forensic population genetics research. However, it is necessary to obtain haplotype reference database, as well as knowing the structure and forensic parameters of the population, in order to obtain a higher degree of certainty in forensic cases. The aim of this study was to investigate the genetic diversity of a sample about 774 healthy unrelated Dai male individuals from Yunnan province, Southwest of China through the analysis of 37 Y chromosomal STR loci included in the Goldeneye™ Y Plus PCR Amplification Kit. Genetic relationships were analyzed using YHRD’s AMOVA tools and MEGA 6.0 software. A total of 548 haplotypes were detected, out of which 420 were unique. The overall haplotype diversity (HD) and discrimination capacity (DC) were 0.9990 and 0.7080, respectively. The gene diversity (GD) ranged from 0.0256 (DYS645) to 0.9141 (DYF404S1). Phylogenetic analysis demonstrated that Tai-Kadai language speaking groups presented a closer genetic relationship than other groups. Our results not only established the Chinese Dai population databases, but also provided valuable information for forensic paternity identification and human genetics.
