Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
Patients who were naïve to lipid-lowering agent or patients who were treated with lipid-lowering agent and had 4 week' wash-out period were enrolled in the study. The eligible patients will be allocated to one of vytorin 10/20 or atorvastatin 10 mg group in 1:1 ratio.

Reporting Groups
  Description
Vytorin Vytorin group- The eligible patients were allocated to one of vytorin 10/20 or atorvastatin 10 mg group in 1:1 ratio. 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 patients achieved LDL-C < 100 mg/dl, they received the same dosage of study drug for the next 6 weeks. Patients who were allocated to vytorin had vytorin 10/20 mg or 10/40 mg tablet, orally, once a day.
Atorvastatin Atorvastatin group- Patients who were allocated to atorvastatin had atorvastatin 10 mg or 20 mg tablet, orally, once a day.
