Data are expressed as mean difference (95% confidence interval).
a
Effective steps levels, Level 1: 4000 ‐ < 8000 Steps/day; Level 2: 8000 ‐ < 10 000 Steps/day; Level 3: 10 000‐ 12 000 Steps/day; Level 4: more than 12 000 Steps/day.
b
ΔSBP: difference of systolic blood pressure change in mm Hg (95% confidence interval).
c
ΔDBP: difference of diastolic blood pressure change in mm Hg (95% confidence interval).
