Researchers conduct a randomized controlled trial to determine if graduated aerobic physical activity reduces post-operative pain more than a graduated resistance exercise intervention. The primary purpose of blinding the investigators for this trial is to avoid: a. non-random (differential) misclassification of exposure status b. observer bias c. surveillance bias d. recall bias

5. A study is planned to assess the effectiveness of a new combination drug for treating nephrolithiasis (kidney stone). One hundred patients with nephrolithiasis will be randomly assigned to receive either the new combination drug or the standard surgical intervention. The efficacy of the new drug will be measured by the time it takes a patient to return to normal activities, measured in days. Identify the appropriate research design for this study a. Prospective cohort study b. Randomized controlled trial...

5. A small study is designed to compare the effectiveness of aripiprazole therapy versus cognitive behavioral therapy in the treatment of borderline personality disorder. Study participants are randomized into groups A and B. Group A will receive aripiprazole for 8 weeks followed by CBT for 8 weeks. Group B will undergo CBT for the first 8 weeks followed by aripiprazole therapy. Participants will complete symptom checklists at both 8 and 16 weeks. Which design best describes this study? A.

In a randomized controlled trial of screening for two forms of cancer (breast and colon), more than 150,000 men and women were recruited to take part. Follow-up of these individuals took place over an average of 5 years for cancer incidence and cause-specific mortality. In an analysis unrelated to those bearing on the efficacy of screening, incidence and mortality rates in all trial participants combined were compared to those of demographically comparable individuals in the population as a whole. The...

> Question 9 3 pts In a randomized, double-blind, placebo-controlled trial of children, echinacea was tested as a treatment for upper respiratory infections in children. "Days of fever" was one criterion used to measure effects. Among 337 children treated with echinacea, the mean number of days with fever was 0.81, with a standard deviation of 1.50 days. Among 370 children given a placebo, the mean number of days with fever was 0.64 with a standard deviation of 1.16 days. Assuming...

6. (3 pts) A randomized clinical trial was conducted in Indonesia to study the effects of Vitamin A in preventing deaths among children with measles. The investigators reported a relative risk of 0.60 for the intervention versus control group. This means that A) Children receiving Vitamin A were 40% less likely to die from measles than children receiving placebo, therefore Vitamin A was protective B) The chance of dying from measles in the placebo group was 60% C) 60% of...

In a randomized double-blind, placebo-controlled trial of children, an herb was tested as a treatment for upper respiratory infections in children. "Days of fever was one criterion used to measure effects. Among 335 children treated with the herb, the mean number of days with fever was 0.78, with a standard deviation of 1.51 days. Among 387 children given a placebo, the mean number of days with fever was 0.56 with a standard deviation of 123 days. Usea 0.01 significance level...
