The table provides the OR (95%CI) relative to the risk of MI associated with the exposure to high serum levels of ApoB, total-cholesterol (tot-chol), LDL-cholesterol (LDL-chol) in the absence of the allele G at rs599839 and of the allele C at rs646776 in the first row of the two sections; the risk associated with the exposure to the allele G or C in the absence of the exposure to high lipid serum levels in the second row of each section and the risk associated with the exposure to both serum levels and genotype in the third row of each section. The last row of each section reports the S index along with the 95%CI.
