1. The problem statement, all variables and given/known data “The risk of celiac disease at 5 years of age was 12.1% (95% CI, 9.2 to 15.0).” The question is: what do they mean with risk a,incidence rate b.cumulative incidence c.attributive risk d.population atrributive risk 2. Relevant equations 3. The attempt at a solution I dont understand how to use this little tekst to decide wether this is an incidence rate or cumulative incidence. Really frustrating.
