What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Percent Change From Baseline in LDL-Cholesterol (mg/dL) After 6 Weeks of Treatment	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.	Baseline to 6 weeks

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Percent Change From Baseline in LDL-Cholesterol (mg/dL) After 6 Weeks of Treatment in Each Stratum	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.	Baseline to 6 weeks
Number of Participants Who Reached Their Target LDL-C Level	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.	6 weeks of treatment
Number of Participants in Each Stratum Who Reached Their Target LDL-C Level	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.	6 weeks of treatment
Number of Participants Who Reached the LDL-C Level of <70 mg/dl	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.	6 weeks of treatment
Number of Participants in Each Stratum Who Reached the LDL-C Level of <70 mg/dl	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).	6 weeks of treatment
Percent Change From Baseline in Other Lipid, Lipoprotein, Apolipoprotein and High-sensitivity C-reactive Protein (Hs-CRP)Levels	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.
