Table 2:

Cross-classification of masked hypertension (MHT) status defined using ambulatory blood pressure monitoring (ABPM) by MHT status defined using home blood pressure monitoring (HBPM)

Classification	Any MHT Status
Home MHT Status	Without Any MHT	Any MHT
Without Home MHT	238 (71.5%, 66.6% – 76.3%)	58 (17.4%, 13.3% – 21.5%)
Home MHT	9 (2.7%, 1.0% – 4.4%)	28 (8.4%, 5.4% – 11.4%)
	Daytime MHT Status
Home MHT Status	Without Daytime MHT	Daytime MHT
Without Home MHT	262 (78.7%, 74.3% – 83.1%)	34 (10.2%, 7.0% – 13.5%)
Home MHT	13 (3.9%, 1.8% – 6.0%)	24 (7.2%, 4.4% – 10.0%)
	24-hour MHT Status
Home MHT Status	Without 24-hour MHT	24-hour MHT
Without Home MHT	260 (78.1%, 73.6% – 82.5%)	36 (10.8%, 7.5% – 14.1%)
Home MHT	14 (4.2%, 2.0% – 6.4%)	23 (6.9%, 4.2% – 9.6%)
	Nighttime MHT Status
Home MHT Status	Without Nighttime MHT	Nighttime MHT
Without Home MHT	251 (75.4%, 70.7% – 80.0%)	45 (13.5%, 9.8% – 17.2%)
Home MHT	17 (5.1%, 2.7% – 7.5%)	20 (6.0%, 3.5% – 8.6%)

Data are expressed as number (percentage, 95% CI)

Any MHT was defined as having daytime MHT, 24-hour MHT, and/or nighttime MHT on ABPM

Daytime MHT was defined as mean SBP ≥ 135 mmHg and/or mean DBP ≥ 85 mmHg using BP readings during the daytime period on ABPM

24-hour MHT was defined as mean SBP ≥ 130 mmHg and/or mean DBP ≥ 80 mmHg using all available readings on ABPM

Nighttime MHT was defined as mean SBP ≥ 120 mmHg and/or mean DBP ≥ 70 mmHg during the nighttime period on ABPM

Home MHT was defined as mean home SBP ≥ 135 mmHg and/or mean DBP ≥ 85 mmHg on HBPM

ABPM: Ambulatory blood pressure monitoring

CI: confident interval

DBP: Diastolic blood pressure

HBPM: Home blood pressure monitoring

MHT: Masked hypertension

SBP: Systolic blood pressure
