Question

Question 27 What is the relatives risk (RR) of having a rise in serum creatinine levels given a patient received gentamicin compared to not receiving gentamicin? a. 1.47 b. 2.32 c. 1.32 Suppose sex is suspected to be a confounder and the breakdown of gentamicin vs. creatinine levels are given below. What is the RR_ ? a. 1.32 b. 1.25 c. 0.98 d. 1.87 True or False: Comparing RR_ (from Q25) to RR_ sex does not appear to be a confounder. The table fives the age and left ventricular ejection fraction for 10 patients with acute dilated cardiomyopathy. The mean age is 40.8 (s = 18.27), the mean LVEF is 0.25 (s= 0.09) and

Explanation / Answer

Answer:

False: comparing RRcrude to RRcmh, sex does not appear to be a confounder.

RRcrude=1.47 and RRcmh=1.87 and the change is 1.87-1.47=0.40 which is 40%.

sex does appear to be a confounder.
