For the UK Biobank the relative atherogenicity (CHD risk quotient) per unit higher Lp(a)-apoB compared to LDL-apoB was 6.6 [95%CI: 5.1-8.8] (Table 2) whilst use of a previously published Lp(a) SNP set gave a risk quotient of 11.8 [95%CI:9.3-15.7] (see Online Figure 4 for a re-evaluation of the previously published SNPs set using the methodology described in the present paper). Here, APOB is linked to coronary artery disorder.
