Methodological issues inherent in designing and analyzing studies with biomarker measurements occur in most of the division's research, often motivating independent methodological research projects. BBB investigators, in collaboration with Epidemiology Branch investigators, are designing new ways to pool biomarker specimens in epidemiologic and clinical studies to increase power and reduce costs, especially in longitudinal studies. Methods for inter-rater agreement and diagnostic accuracy are other important biomarker-related areas of BBB research born from the division’s collaborative focus.
