Webbför 2 dagar sedan · Association analysis between SNPs and anti-VZV IgG, as well as SNP clumping, was conducted using PLINK v1.9. Data We used anti-VZV IgG levels as the exposure. The summary statistics (estimated SNP effects and their standard errors) were extracted from our SNP-anti-VZV IgG association analysis. WebbPLINK will generate a number of standard summary statistics that are useful for quality control (e.g. missing genotype rate, minor allele frequency, Hardy-Weinberg equilibrium failures and non-Mendelian transmission rates). These can also be used as thresholds …
