Question 350359: I need someone to fully explain how to get this answer ns easy terms. Please include step by step instructions to figure this out. I am struggling with this class and have other questions to answer. Thank you for your help!
A clinical trial is conducted to compare an experimental medication to placebo to reduce the symptoms of asthma. Two hundred participants enrolled in the study and randomized to receive either the experimental medication or placebo. The primary outcome is a self-reported reduction of symptoms. Among 100 participants who received the experimental medication, 38 reported a reduction of symptoms as compared to 21 participants of 100 assigned to the placebo.
a. Generate a 95% CI for the difference in proportions of participants reporting a reduction of symptoms between the experimental and the placebo groups?
b. Estimate the RR for reduction in symptoms between groups?
c. Estimate the OR for reduction in symptoms between groups?
d. Generate a 95% CI for the RR?
