Recall the definitions of relative and excess risk from your lectures. One of the cases given in the paper "Diagnostic radiography in pregnancy: Risks and reality" had a case where 792 children died from leukemia, in a population of 275,000. If the normal incidence is 150/100,000, what are the relative and excess risks in this situation?Group of answer choices0.52, and 9/31252.88, and 1/200,0001.92, and 69/50,0001.94, and 31/22000

What are relative risks?

What is the definition of relative risk?Question 1Answera.One minus the risk ratiob.The number of patients you need to give an intervention to to prevent one additional negative outcomec.The difference in proportion of subjects with the outcome of interest in each groupd.The probability of an event in the treatment group divided by the probability of an event in the control group

11,000 people in an area around a large nuclear power plant were followed for 7 years, or until the development of any cancer of the blood. 30 cases were identified over the 7 year study period.What is the risk of developing the outcome of interest: cancer of the blood?.27 or 27%.0027 or .27%366.02 or 2%
