Figure 4From: Genome-Wide Association Study of Determinants of Anti-Cyclic Citrullinated Peptide Antibody Titer in Adults with Rheumatoid ArthritisQuantile-Quantile plot (Q-Q) showing the comparison between whole genome association observed -log10(p) and expected -log10(p). Expected -log10(p) assumes there is no association between SNPs with anti-CCP and shown on the abscissa. The observed -log10(p) is shown on the ordinate.Back to article page
