a
Data are means ± SD.
b
Paired t test was used for determination of the difference between baseline and endpoint values in each group.
c
ANOVA was used for examining the significance of the difference in changes of variables between the two groups. BMI, body mass index; SBP, systolic blood pressure; and DBP, diastolic blood pressure.
d
ANCOVA was used for examining the significance of the difference between the two groups with baseline values as a confounder.
