FIGURE 1.
Percent concordance of familial relationships identified by KING compared with PLINK by survey. KING relationships were considered concordant if also identified by PLINK (expressed as percent on the y-axis). We only consider close relationships here (monozygotic or MZ twins, duplicate samples, and parent-offspring) in estimating concordance given the limited SNP data and the lack of resolution expected with these data. The data are displayed by Genetic NHANES (x-axis) and stratified by estimated familial relationship and race/ethnicity.
