A genomewide association study in the INTERVAL and UK Biobank studies, testing 29.5 million genetic variants for association with 36 red cell, 
white cell, and platelet traits in 173,480 European-ancestry participants.  The paper describing these results was published 
in Cell in November 2016: Astle, William J., Elding, H., Jiang, T., et al. The Allelic Landscape of Human Blood Cell Trait Variation and 
Links to Common Complex Disease. Cell 167, 1415-1429.e1419.
