Concerning the mean difference of total cholesterol (Table 1) between the A. sativum and the 0.9% PS groups, we obtained 32.150 mg/dL with 95% CI varying from -41.384 to 105.684 mg/dL. The mean difference between the cilostazol and 0.9% PS groups was -26.750 mg/dL, with 95% CI varying from -100.284 to 46.784 mg/dL. However, between the cilostazol and A. sativum groups, the mean difference was -58.900 mg/dL with 95% CI from -132.434 to 14.634 mg/dL. From two-way ANOVA, we obtained P=0.0165; however, the results were not significant in the Tukey test. Thus, there was no difference between groups in total cholesterol.
