Table 2. The occurrence of CHD and lipid and lipoprotein levels divided into quartiles of apoB/apoA1 ratio in the overweight group.

CHD [n(%)]	66(66)	72(71)	74(75)	88(89)	< 0.001
TG (mmol/L)	1.55 ± 0.81	1.92 ± 1.15	2.04 ± 1.44	2.21 ± 1.19	< 0.001

^aP-Value refers to difference between quartiles 1 and 4. CHD: coronary heart disease; TC: total cholesterol; TG: triglyceride; LDL-C: low density lipoprotein cholesterol; HDL-C: high density lipoprotein cholesterol.
