APOB and coronary atherosclerosis: The logistic regression analysis showed consistent results, as the LDL/ApoB ratio was negatively associated with the presence of coronary atherosclerosis (B = −0.593, p = 0.010, OR 0.553, 95% CI: 0.352–0.867, R2 = 0.096); however, it showed a limited predictive power for significant CAD.
