Answered step-by-step
Asked by mimioseke

The results shown are based on a comparison of the last 100 patients treated before the CCU was installed and the first 100 patients treated within the CCU. All 200 patients were admitted during the same month. You may assume that this is the only hospital in the town and that the natural history of MI was unchanged during this period.

5 The authors concluded that the CCU was very beneficial for men with severe MI and for those in shock, because the in-hospital CFs for these categories were much lower in the CCU. This conclusion:

a. Is correct

b. May be incorrect because CFs were used rather than mortality rates

c. May be incorrect because of a referral bias of patients to this hospital from hospitals in

distant towns

d. May be incorrect because of differences in the assignment of the clinical severity grade

before and after the opening of the CCU

e. May be incorrect because of failure to recognize a possible decrease in the annual

incidence rate of MI in recent years

Give a well detailed rationale for your answer
