ARV, average real variability; DBP, diastolic blood pressure; SBP, systolic blood pressure; SD, standard deviation; wSD, time‐weighted standard deviation.
Values were presented as mean ± standard deviation. Student t‐test was applied to compare variables between men and women, and the P values were shown on the right column.
