  1. ξ Systolic blood pressure ≥ 140 and/or diastolic ≥ 90 mm Hg [41]
  2. # BSA = square root ((height in cm × weight in kg)/3600).
  3. The intraclass correlation coefficient (ICC) is the between- subject minus the within- subject variance as a ratio to the sum of the two variances. A positive value of, for instance, 0.60 indicates that 60% of the variation is due to between-subject and 40% due to within-subject variance. ICC can become negative when the within-subject variance exceeds the between-subject variance.
