1) Attributable risk = Incidence in exposed - Incidence in Unexposed

Questions asking the risk of developing cirrhosis if exposed to Alcohol =

Incidence of cirrhosis in alcoholics = 63/1000
Incidence of cirrhosis in non-alcoholics = 7/1000

Subtract the two and the answer will be = C) 56:1000

Hope that's right.

2) Absolute risk in 2008 ... not sure what the risk would be in 2008 .. same as in 2011 ? then i'd go with B) 63:1000

Thanks for your note.
The first: Answer is C.

The second: is E) 21:1000
Because the absolute risk is the incidence of cirrhosis among people in Dublin in 2008, not just alcoholics.
