Pencina, Ph.D., of the Duke College Medical Middle, Durham, N.C., and colleagues pooled particular person patient-level knowledge from 5 observational cohort research out there within the Nationwide Coronary heart, Lung, and Blood Institute Biologic Specimen and Knowledge Repository Info Coordinating Middle.
