title: The promise and realities of comparative effectiveness research.
abstract: Comparative Effectiveness Research (CER) has been given a broad and ambitious mandate. Will it be able to deliver the multifaceted and granular comparative information that it has been tasked with developing? After a discussion of the general conditions for the feasibility of CER, we focus our attention on one of the most challenging areas: the evaluation of diagnostic tests and biomarkers.
