1p-value from unpaired two-samples t-test with equal variance; 2p-value from Ancova models adjusted for gender and BMI (baseline).
SD – standard deviation, V1 – initial visit, V2 – final visit, SBP - systolic blood pressure, DBP - diastolic blood pressure, HBPM – home blood pressure measurement, PWV – pulse wave velocity, FMD – flow mediated dilation.
