Key result
The white-coat effect was inversely correlated with daytime ambulatory systolic (r = -0.22, P<0.000) and diastolic (r = -0.50, P<0.000) blood pressure, with no association to left ventricular mass.
Why the study?
How does the white-coat effect vary with daytime ambulatory blood pressure levels, and is it associated with left ventricular mass?

How does the white-coat effect vary with daytime ambulatory blood pressure levels, and is it associated with left ventricular mass?
Effect estimate: r = -0.22 (systolic), r = -0.50 (diastolic)
p-value: p=< 0.000
The white-coat effect is inversely associated with daytime ambulatory blood pressure levels and does not correlate with left ventricular mass, suggesting it may not independently drive target organ damage.
Zakopoulos et al. (2002) conducted a cross-sectional in Normotension and hypertension (n=1,581). Daytime ambulatory blood pressure was evaluated on Correlation between white-coat effect and daytime ambulatory blood pressure (r = -0.22 (systolic), r = -0.50 (diastolic), p=< 0.000). The white-coat effect was inversely correlated with daytime ambulatory systolic (r = -0.22, P<0.000) and diastolic (r = -0.50, P<0.000) blood pressure, with no association to left ventricular mass.
