question 500

Multiple Choice

Researchers are conducting a cross-sectional study to demonstrate the relationship between renal frame count (RFC) , considered the dependent variable, and LDL, considered an independent variable.  RFC is an objective quantitative angiographic method of measuring macrovascular blood flow in the main renal artery and its segmental branches.  Two hundred patients were categorized into 2 groups according to serum LDL levels-LDL <130 mg/dL (n = 90) and LDL ≥130 mg/dL (n = 110) .  Other parameters included BMI, platelet count, and creatinine clearance.  Which of the following is the best statistical approach for simultaneously evaluating the association between RFC and LDL cholesterol while adjusting for BMI, platelet count, and creatinine clearance?

• A)Multiple linear regression
• B)Multiple logistic regression
• C)One-way analysis of variance
• D)Pearson correlation analysis
