This work proposes summarizing the discrimination potential of a marker X, measured at baseline (t = 0), by calculating ROC curves for cumulative disease or death incidence by time t, which is presented as ROC(t), and presents an example where ROC (t) is used to compare a standard and a modified flow cytometry measurement for predicting survival after detection of breast cancer.
Genome-wide association study of blood pressure and hypertension
A genome-wide association study of systolic (SBP) and diastolic (DBP) blood pressure and hypertension in the CHARGE Consortium identifies 13 SNPs for SBP, 20 for DBP and 10 for hypertension at P < 4 × 10−7.

Although CLU and PICALM were confirmed to be associated with AD in this independent sample, they did not improve the ability of a model that included age, sex, and APOE to predict incident AD.
Systematic identification of trans eQTLs as putative drivers of known disease associations
Variants associated with cholesterol metabolism and type 1 diabetes showed similar phenomena, indicating that large-scale eQTL mapping provides insight into the downstream effects of many trait-associated variants.
