APOB and coronary atherosclerosis: However, when testing for the presence of coronary atherosclerosis, the LDL/ApoB ratio was negatively associated with the disease (B = −0.593, p = 0.010, OR 0.553, 95% CI: 0.352–0.867, R2 = 0.096), suggesting that a lower ratio is linked to a greater likelihood of coronary disease.
