Correlation coefficients (β) between markers of arterial stiffness in multiple linear regression analysis

	24‐h PP (mmHg)	baPWV (cm/s)
AASI	0.507**	—
baPWV (cm/s)	0.352**	—
ABI	−0.040	0.015
AIx@75	0.149*	0.324**

Significant correlations of arterial stiffness factors in unadjusted Pearson's coefficient were put in multivariate linear regression. Adjusted for age, sex, diabetes, 24 h SBP, 24 h DBP, eGFR and 24 h proteinuria. Significance of the correlation coefficients: *p < .05, **p < .01.

Abbreviations: 24 h PP, 24‐h  pulse pressure; AASI, ambulatory arterial stiffness index; ABI, ankle‐brachial index; AIx@75, augmentation index standardized to a heart rate of 75 ; baPWV, brachial‐ankle pulse wave velocity. Correlation coefficients (β) were standardized beta coefficients derived from linear regression analysis with 24‐h PP and baPWV as dependent variables.
