3. Compare two treatments. Treatment A provides an improvement of 0.1 QALYs at a cost of $2,000, whereas Treatment B provides an improvement of 0.2 QALYs at a cost of $5,000. a. Calculate the CEA ratio b. What does the number you calculated mean? C. If it was only possible to choose treatment A OR treatment B, and each one can only be done one time, how would you use the CEA ratio to decide whether to choose treatment A or B? d. If you could repeat either treatment as many times as you wanted, how would this change your answer? If you need to make any assumptions to answer, be clear about what they are. 3.
