Final regression model of correlates of K1R (N = 122)

Model parameter	Standardized β coefficient	p value	Incremental R2
Age	− 0.510	0.0001	0.441
TPRb	− 0.151	0.009	0.095
Systolic pressurea	− 0.517	0.0001	0.053
Gender	0.267	0.0001	0.030
Heart ratea	0.212	0.007	0.023

Total R² = 0.64 (Model: p < 0.0001)

The potential predictors of K1R included in these procedures were: age, gender, height, weight, SP (as determined from the K2 algorithm), HR, TPR, CO, stiffness index (β), arterial compliance (SV/PP), LVM, LVM index, LVRWT, aortic diameter, CARWT, CIMTd, presence of carotid plaque, and CSA (surrogate for Vascular Mass)
