In the multivariate variable-adjusted model, the OR and 95% CI of intermediate levels of ApoB (0.85-1.05 g/L) compared with low levels of ApoB (≤0.84 g/L) and residual risk after myocardial infarction was 2.06 (1.11,3.81) (P<0.05), and the OR and 95% CI of high-levels of ApoB (≥1.06 g/L) associated with the occurrence of adverse cardiovascular events after myocardial infarction with an OR and 95% CI of 2.60 (1.29,5.26) (P<0.05) (Table 4); the risk of adverse cardiovascular events after myocardial infarction would increase 4.75-fold for each SD increase in ApoB levels (P=0.003) (Table 4). The gene discussed is APOB; the disease is myocardial infarction.
