Effect of policosanol on serum lipid levels. (a) In Protocol I, serum low-density lipoprotein cholesterol levels decreased significantly at 8 weeks compared with baseline in both treatment groups (both P < 0.01, shown as “∗”). (b) In contrast with Protocol I, serum low-density lipoprotein cholesterol levels did not decrease significantly even at 12 weeks compared with baseline in both treatment groups in Protocol II (both P > 0.05). (c) In Protocol I, the extent of the low-density lipoprotein cholesterol decrease between the atorvastatin group and the policosanol + atorvastatin group was not statistically significant (−38.5% versus −35.3%, P = 0.692). Similarly, in Protocol II, the change of the low-density lipoprotein cholesterol between the policosanol group and control group was not statistically significant (1.1% versus 2.7%, P = 0.769).
