Fig. 5From: Establishing analytical validity of BeadChip array genotype data by comparison to whole-genome sequence and standard benchmark datasetsBar plot of percentage of GSA assays with a positive predictive value (PPV) < 1 as a function of alternate allele frequency bins (allele frequency bins as percentage). The alternate allele frequency bins were defined based on the frequency information in 1000 Genomes (1KG) dataBack to article page
