Multivariable linear regression model for morning-evening blood pressure difference.

Variable	Beta-coefficient   (95% CI)	P value
Systolic morning-evening home BP difference
Age	0.12 (0.03–0.21)	0.007
Smoking habit	−7.52 (−11.44–[−3.61])	<0.0001
Diastolic morning-evening home BP difference
Age	0.07 (0.03–0.12)	0.001
Total cholesterol	0.99 (0.38–1.6)	0.002
CCB use	1.44 (0.21–2.66)	0.02
Smoking habit	−2.91 (−4.81–[−1.02])	0.003

Adjusted R ² values for the model were 6.2% for systolic and 8.5% (P < 0.0001) for diastolic morning-evening BP difference, respectively.
