Genome-wide scan for RA-SNP association. The p-values < 0.05 from single SNP association tests were plotted in -log10 scale against chromosomal positions of the corresponding 48,366 SNPs. Blue and light blue were used to distinguish chromosomes. Red indicates potential RA-related SNPs that were identified by fitting the penalized logistic regression model (M1) via elastic-net using top 3000 of those 48,366 SNPs.
