The correlation coefficient (r) was estimated by the Pearson’s correlation analysis (n = 103). Abbreviations: SD, standard deviation; CV, coefficient of variation; SBPV, systolic blood pressure variability; DBPV, diastolic blood pressure variability
*p < 0.05
**p < 0.01
†Blood pressure variability measured by the standard deviation,
