Examination of "Early Mortality Exclusion" as an Approach to Control for Confounding by Occult Disease in Epidemiologic Studies of Mortality Risk Factors [PDF]
American Journal of Epidemiology, 1997 Methods for the estimation of the effects of chronic disease risk factors on mortality continue to be an area that generates confusion and controversy. In response to the frequently observed U- or J-shaped relations between risk factors and mortality, some authors suggest that subjects dying during the first k years of follow-up (where k is some ...
