http://www.w3.org/ns/prov#value | - question is whether there is a need to ensure normal concentrations of calcidiol ??? or calcitriol ??? in addition to the use of a VDR analogue.Can we clinically influence RAS com-ponents in vivo in humans with VDR acti-vators without side effects; does this have an influence on the progression of renal disease; and what doses are needed?
