ESTIMATION OF MULTIPLE RELATIVE RISK FUNCTIONS IN MATCHED CASE-CONTROL STUDIES

摘要: A linear logistic model used to estimate multiple risk functions in both cohort and case-control studies is adapted for sampling plans wherein each case matched with R controls. The resulting methodology substantially liberalizes current practice by permitting simultaneous analysis of discrete continuous factors. Interactions among factors, between factors matching variables, may be explored. Data from two oesophageal cancer, one conducted Singapore Chinese the other on Caspian littoral Iran, illustrate methods.
