The incidence of carcinoma cervix in women with multiple sexual paners is 5 times the incidence seen in those with a single paner. Based on this, what is the attributable risk?
- If the incidence of carcinoma cervix in those with single paner is 'I' , then the incidence in those with multiple sexual paners will be 5 'I'. - Now attributable risk = (Incidence in exposed-Incidence in non-exposed/Incidence in exposed ) X 100 = (5I-I / 5I) X 100 = (4/5) X 100 = 80%.
