A longitudinal study evaluates the long-term complications in diabetic patients treated under two competing treatment regimens. Complications are measured by the incidence for foot disease, eye disease, or cardiovascular disease within a 10-year observation period. The following 2x2 cross-tabulation table summarizes the data. Long-term Complications Treatment Total F Yes No- Treatment1 - 12- 88 100- Treatment2 23 8- 92- 100- Total 20- 180- 200- a. Estimate the relative risk of the incidences of complications for treatment 1 versus treatment 2 b. Is there a difference in the incidences of complications on different treatment group? Run the appropriate test at a-0.05. Critical value of ² (df-1) is 3.84.

A longitudinal study evaluates the long-term complications in diabetic patients treated under two competing treatment regimens. Complications are measured by the incidence for foot disease, eye disease, or cardiovascular disease within a 10-year observation period. The following 2×2 cross-tabulation table summarizes the data. Long-term Complications - Treatment >> Total - Yes No. Treatment1. 12- 05 88 100 - Treatment2- 8. 92- 100- 19 Total - 20- 19 180- 5 200- a. Estimate the relative risk of the incidences of complications for treatment 1 versus treatment 2 b. Is there a difference in the incidences of complications on different treatment group? Run the appropriate test at a-0.05. Critical value of ² (df-1) is 3.84.
