Outcome results
Number of Participants Reaching the LDL-C (Low Density Lipoprotein-Cholesterol) Goal (< 100 mg/dl) After 6 Weeks of Treatment
Primary objective is to evaluate the proportion of patients achieving LDL-C target \<100 mg/dl recommend in National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III) after 6 weeks of treatment(vytorin 10/20 vs. atorvastatin 10 mg)
Time frame: After 6 weeks of treatment
Population: The analysis used all patient treated (APT) approach which included all patients who had baseline measured right before randomization, have taken the study drug more than once after randomization and have one measurement after the initiation of the treatment.

|---|---|---|
| Vytorin | Number of Participants Reaching the LDL-C (Low Density Lipoprotein-Cholesterol) Goal (< 100 mg/dl) After 6 Weeks of Treatment | 89 Participants |

Number of Participants Reaching the LDL-C Goal (< 100 mg/dl) After 12 Weeks of Treatment
If patients didn't achieve LDL-C \<100 mg/dl after 6 weeks of treatment, they received the double dosage of study drug for the next 6 weeks (vytorin 10/40 or atorvastatin 20 mg) and If achieved LDL-C \< 100 mg/dl, they received the same dosage of study drug for the next 6 weeks.
Time frame: After 12 weeks of the treatment
Population: All patient treated (APT) approach

|---|---|---|
| Vytorin | Number of Participants Reaching the LDL-C Goal (< 100 mg/dl) After 12 Weeks of Treatment | 85 Participants |
