Association Between Presence of the WCE and Presence of Hypertension by Conventional BP Measurement
| Hypertension Present (≥140/90 mm Hg) | Grade II Hypertension Present (≥160/100–179/109 mm Hg) | Grade III Hypertension Present (≥180/110 mm Hg) | Isolated Systolic Hypertension | |
|---|---|---|---|---|
| Systolic BP | 171.8 (26.79) | 169.6 (17.03) | 205.0 (16.46) | 162.4 (19.27) |
| Diastolic BP | 89.7 (12.06) | 92.3 (10.14) | 98.1 (13.60) | 81.6 (6.22) |
| WCE present (n=54) | 48 (88.9%) | 14 (61.1%) | 19 (35.2%) | 26 (48.1%) |
| WCE absent (n=25) | 14 (56.0%) | 4 (16.0%) | 1 (4.0%) | 10 (40.0%) |
| Significance | χ2 (1)=10.945, P=.001 | χ2 (1)=13.966, P<.001 | χ2 (1)=8.790, P=.003 | χ2 (1)=0.457, P=.499 |
Abbreviations: BP, blood pressure; WCE, white‐coat effect. Values are presented as mean (standard deviation) or number (percentage).
