Assume that 1,000 subjects in each age cohort have been followed until age 65, have survived, but have developed ESRD. Calculate the risk difference (i.e., difference in rates), the cumulative incidence in each age group, the total costs of this complication, and the savings that can be attributable to screening. The model assumes that ESRD is associated with costs of $68,131 per person per year.

Age Group	Incidence Screened	Incidence Unscreened	Risk Difference	#ESRD Unscreened	#ESRD Screened	Cost Unscreened ($)	Cost Screened ($)	Savings
25-34	159	192	33
35-44	80	103	23
45-54	30	42	12
55-64	9	14	5
65+	2	3	1
