Difference in Means of Matched/Unmatched Monitor Blood Pressure Readings From Mean Unmatched Readings: Mean Unmatched Systolic (or Diastolic) Reading − Mean Matched Systolic (or Diastolic) Reading

Mean Difference Systolic	Number of Patients	Percent of Patients
More than −10 mmHg	7	14.3
−5 to −10 mmHg	4	8.2
−2 to −5 mmHg	5	10.2
−2 to 0 mmHg	5	10.2
0–2 mmHg	2	4.1
2–5 mmHg	11	22.4
5–10 mmHg	11	22.4
More than +10 mmHg	4	8.2
Mean Difference Diastolic	Number of Patients	Percent of Patients
More than −10 mmHg	1	2.0
−5 to −10 mmHg	3	6.1
−2 to −5 mmHg	3	6.1
−2 to 0 mmHg	5	10.2
0–2 mmHg	8	16.4
2–5 mmHg	15	30.6
5–10 mmHg	10	20.4
More than +10 mmHg	4	8.2
Data were calculated by subtracting mean matched reading from mean unmatched readings: mean unmatched systolic (ordiastolic) reading minus mean matched systolic (ordiastolic) reading.
