9/217 (4.1%) | 3/217 (1.4%) | 1/217 (0.5%) | 5/217 (2.3%) |
Combined: Systolic and/or Diastolic Inter-arm Blood Pressure Difference ≥ 10 mm Hg | |||
1st measurement | 2nd measurement | Patients with IAD in 1st & 2nd measurements | Averaged measurements |
29/217* (13.3%) | 20/217** (9.2%) | 8/217 (3.6%) | 31/217 (14.2%) |
