A study was carried out to monitor mortality rates resulting from coronary heart disease (CHD) in people with and without diabetes. The data show the coronary heart disease mortality rates for two time periods.
Using the data, evaluate the claim that patients with diabetes have a higher risk of mortality from CHD.
[2]
a. claim supported for 87–96 data since patients without diabetes have lower mortality rate due to CHD
b. claim possibly not supported for the 03–09 data since rate of CHD mortality is similar for the two groups
c. mortality due to CHD in diabetes patients has decreased / mortality for non-diabetics has increased
d. large variance/error bars/overlapping error bars for 03–09 do not allow firm conclusion
e. no data on gender/age/obesity, etc.
Accept converse answers.
