Central blood pressures and stiffness measurements were obtained from 37 subjects in the placebo and 38 subjects in the vitamin D arms, respectively.

25OH Vitamin D = 25-hydroxyvitamin D.

DBP  =  diastolic blood pressure.

FMD  =  flow-mediated dilation.

HDL  =  high density lipoprotein.

LDL  =  low density lipoprotein.

SBP  =  systolic blood pressure.
