APOB and metabolic syndrome: Increase in the number of MetS components is associated with an OR of 1.8 (P < 0.001) to exhibit plasma apoB > 0.9 mmol/L among subjects with LDL-C < 3.5 mmol/L, whereas the relation between both variables is non-significant in subjects with LDL-C ≥ 3.5 mmol/L (OR = 1.1; P = 0.58).
