The first initiative within the broader Project Baseline has just began: the longitudinal study will collect broad phenotypic health data from approximately 10 thousands participants, who will each be followed over the course of at least four years. The project is managed under a partnership between Verily Life Sciences, an Alphabet company, Duke University School of Medicine and Stanford Medicine. Project Baseline represents an effort designed to develop a well-defined reference, or “baseline,” of health as well as a rich data platform that may be used to better understand the transition from health to disease and identify additional risk factors for disease.
