The REVEAL study is a randomized, controlled study of the psychological and behavioral impact of APOE disclosure in a risk assessment protocol provided to first degree relatives of patients with Alzheimer’s disease. The protocol presents risk information as cumulative incidence curves. This article describes how these curves were estimated.Methods:
Curves were calculated using Bayes’ rule to compute the posterior survival curves incorporating APOE information.Results:
A combination of survival data from the MIRAGE study and gender- and age-specific APOE odds ratios were used to create risk curves for males and females within each of the 6 APOE genotypes.Conclusion:
Utilizing comparative genotype relative risk information and survival data from family studies, estimates of gender-, age-, and genotype-specific risk can be generated for use in a risk assessment research study that features genotype disclosure.
