Abstract:
|
The relative risk, odds ratio, risk difference and attributable risk are the frequently used epidemiological indices in public health and biomedical research to measure the effect of a risk factor in disease development. The recently proposed impact measures added a new dimension in epidemiological research because of their interpretational simplicities. This paper presents methods to compute confidence intervals for impact numbers for a case-control study design. We also consider an example to investigate the impact of the family history of lung cancer on the development of the of non-small-cell-lung cancer in women aged 18 to 74 years in metropolitan Detroit area.
