Figure 1: Comparison between the most recent (COGS) and previous (Turnbull) estimates of risk from the first 18 SNPs to be identified. Plot (a) shows a histogram of relative risks and absolute risk for a woman aged 50; (b) shows initial and the most recent COGS odds ratios (relative to the population) for the risk alleles from the first 18 SNPs; an ordinary least squares linear regression line is shown with slope 0.64.
