Key result
A 1.0 mm Hg increase in daytime systolic blood pressure variability was independently associated with a 0.589 mm Hg increment in the systolic white-coat effect (95% CI 0.437-0.741; P<0.001).
Population
2004 subjects who underwent office BP measurements and 24-h ambulatory BP monitoring (ABPM) on the same day

Patient factors may modulate WCE magnitude; hypothesis-generating for refined ABPM interpretation in hypertension.
Cross-Sectional (n=2,004)
Mean Difference: 0.589 (95% CI 0.437–0.741)

Factors such as gender, age, smoking, office BP, and daytime BP variability independently influence the magnitude of the white-coat effect.
MANIOS et al. (2008) conducted a cross-sectional in White-coat effect (n=2,004). Daytime systolic blood pressure variability was evaluated on Systolic white-coat effect (beta 0.589, 95% CI 0.437-0.741, p=<0.001). A 1.0 mm Hg increase in daytime systolic blood pressure variability was independently associated with a 0.589 mm Hg increment in the systolic white-coat effect (95% CI 0.437-0.741; P<0.001).
