Allele and Haplotype Diversity of 26 X-STR Loci in Four Nationality Populations from China.
Trial report in PloS one, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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.
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
backgroundHaplotype analysis of closely associated markers has proven to be a powerful tool in kinship analysis, especially when short tandem repeats (STR) fail to resolve uncertainty in relationship analysis. STR located on the X chromosome show stronger linkage disequilibrium compared with autosomal STR. So, it is necessary to estimate the haplotype frequencies directly from population studies as linkage disequilibrium is population-specific. METHODOLOGY AND
findingsTwenty-six X-STR loci including six clusters of linked markers DXS6807-DXS8378-DXS9902(Xp22), DXS7132-DXS10079-DXS10074-DXS10075-DXS981 (Xq12), DXS6801-DXS6809-DXS6789-DXS6799(Xq21), DXS7424-DXS101-DXS7133(Xq22), DXS6804-GATA172D05(Xq23), DXS8377-DXS7423 (Xq28) and the loci DXS6800, DXS6803, DXS9898, GATA165B12, DXS6854, HPRTB and GATA31E08 were typed in four nationality (Han, Uigur, Kazakh and Mongol) samples from China (n = 1522, 876 males and 646 females). Allele and haplotype frequency as well as linkage disequilibrium data for kinship calculation were observed. The allele frequency distribution among different populations was compared. A total of 5-20 alleles for each locus were observed and altogether 289 alleles for all the selected loci were found. Allele frequency distribution for most X-STR loci is different in different populations. A total of 876 male samples were investigated by haplotype analysis and for linkage disequilibrium. A total of 89, 703, 335, 147, 39 and 63 haplotypes were observed. Haplotype diversity was 0.9584, 0.9994, 0.9935, 0.9736, 0.9427 and 0.9571 for cluster I, II, III, IV, V and VI, respectively. Eighty-two percent of the haplotype of cluster IIwas found only once. And 94% of the haplotype of cluster III show a frequency of <1%.
conclusionsThese results indicate that allele frequency distribution for most X-STR loci is population-specific and haplotypes of six clusters provide a powerful tool for kinship testing and relationship investigation. So it is necessary to obtain allele frequency and haplotypes data of the linked loci for forensic application.
