* No change or change in dose or number of hypertension medications.
# Interaction.
a Model was adjusted for vitamin doses group, age, sex, BMI at 6 and 12 months, baseline SBP/DBP, no change or change in dose or number of hypertension medications, time, and included an interaction between vitamin doses group and time.
