Reclassification of White-Coat and Masked Hypertensive Participants

Time Intervals Used for Reclassification White-Coat Hypertension
Masked Hypertension
Original Intervals Maintaining White-Coat Hypertension Reclassified to Sustained Hypertension Original Intervals Maintaining Masked Hypertension Reclassified to Normotension
From daytime to 24 h 747 642 (85.9) 105 (14.1) 1105 668 (60.5) 437 (39.5)
From nighttime to 24 h 1027 724 (70.5) 303 (29.5) 982 566 (57.6) 416 (42.4)
From daytime to 24 h plus daytime and nighttime 747 515 (68.9) 232 (31.1) 1105 1105 (100) 0
From nighttime to 24 h plus daytime and nighttime 1027 515 (50.1) 512 (49.9) 982 982 (100) 0
From 24 h to 24 h plus daytime and nighttime 881 515 (58.5) 366 (41.5) 800 800 (100) 0

Values are number of participants (reclassification rates, %) of white-coat and masked hypertensive participants from the commonly used definitions based on daytime, nighttime, or 24-hour ambulatory blood pressure to one of the other definitions. The McNemar–Bowker test for symmetry along the diagonal of the matrix was significant for all rows (P<0.0001).
