Figure 2 Genome-wide view of the single-point association data based on allele frequencies in a comparison of 71 HCV Japanese patients with LP and 190 patients with HCV without OLP. P values were calculated using the chi-square test for allele frequencies among 629,553 SNPs.

Supplementary Figure 2 Quantile-Quantile plot of the allele-based Chi-square test statistics for the GWAS results. The dots represent the P values of each SNP that passed the quality control filters. The inflation factor λ was estimated to be 1.027 for all the tested.
