Primary Outcome Measures:
  • Percent Change From Baseline in LDL-Cholesterol (mg/dL) After 6 Weeks of Treatment [ Time Frame: Baseline to 6 weeks ] [ Designated as safety issue: No ]
    The percent change from baseline in LDL-C (mg/dL) after 6 weeks of treatment in participants who were administered ezetimibe 10 mg to rosuvastatin (5 or 10 mg) in comparison with doubling the baseline dose of rosuvastatin (10 or 20 mg) daily for 6 weeks.


Secondary Outcome Measures:
  • Percent Change From Baseline in LDL-Cholesterol (mg/dL) After 6 Weeks of Treatment in Each Stratum [ Time Frame: Baseline to 6 weeks ] [ Designated as safety issue: No ]
    The percent change from baseline in LDL-C (mg/dL) after 6 weeks of treatment by stratum I and stratum II in participants who were administered with ezetimibe 10 mg to rosuvastatin (5 or 10 mg) in comparison with the doubling of the baseline dose of rosuvastatin (10 or 20 mg) daily for 6 weeks.

  • Number of Participants Who Reached Their Target LDL-C Level [ Time Frame: 6 weeks of treatment ] [ Designated as safety issue: No ]
    Participants were analyzed to evaluate the LDL-C (<100 mg/dL for moderately high risk patients and high risk patients without AVD and <70 mg/dL for high risk patients with AVD) lowering efficacy with the addition of ezetimibe 10 mg to (5 or 10 mg) compared with doubling the baseline rosuvastatin (10 or 20 mg), daily for 6 weeks of treatment.

  • Number of Participants in Each Stratum Who Reached Their Target LDL-C Level [ Time Frame: 6 weeks of treatment ] [ Designated as safety issue: No ]
    Participants in stratum I were analyzed to evaluate the LDL-C lowering efficacy with the additional of ezetimibe 10 mg to rosuvastatin 5 mg daily for 6 weeks compared with doubling the baseline dose to rosuvastatin 10 mg daily for 6 weeks. Participants in stratum II were analyzed to evaluate the LDL-C lowering efficacy with the additional of ezetimibe 10 mg to rosuvastatin 10 mg daily for 6 weeks compared with doubling the baseline dose to rosuvastatin 20 mg daily for 6 weeks.

  • Number of Participants Who Reached the LDL-C Level of <70 mg/dl [ Time Frame: 6 weeks of treatment ] [ Designated as safety issue: No ]
    Participants across all strata who reached the LDL-C Level of <70 mg/dl after the addition of ezetimibe 10 mg to rosuvastatin (5 or 10 mg) daily for 6 weeks compared with doubling the baseline dose of rosuvastatin (10 or 20 mg) daily for 6 weeks.

  • Number of Participants in Each Stratum Who Reached the LDL-C Level of <70 mg/dl [ Time Frame: 6 weeks of treatment ] [ Designated as safety issue: No ]
    Participants in stratum I and in stratum II who reached the LDL-C Level of <70 mg/dl after the addition of ezetimibe to rosuvastatin (5 or 10 mg)daily for 6 weeks compared with doubling the baseline dose of rosuvastatin (10 or 20 mg).

  • Percent Change From Baseline in Other Lipid, Lipoprotein, Apolipoprotein and High-sensitivity C-reactive Protein (Hs-CRP)Levels [ Time Frame: Baseline to 6 weeks ] [ Designated as safety issue: No ]
    Participants who were analyzed to assess the Total Cholesterol (TC), Triglycerides, High-Density Lipoprotein Cholesterol, Non High-Density Lipoprotein Cholesterol, LDL Cholesterol/HDL Cholesterol, Total Cholesterol/HDL Cholesterol, Non-HDL Cholesterol/HDL Cholesterol, Apolipoprotein B (Apo B), Apolipoprotein A-I (Apo A-I), Apolipoprotein B/Apo A-I, high-sensitivity C-reactive protein (hs-CRP)levels after 6 weeks of treatment.
