Table 6

Multivariate analysis—stepwise logistic regression.

Variable	OR	95% CI for OR		value
		Lower limit	Upper limit
IVRT (ms)	1.045	1.009	1.982	0.01
NT-proBNP (pg/mL)	1.003	1.001	1.005	0.007
LAVI (mL/m^2)	1.3	1.099	1.537	0.002
AIx75	1.095	1.004	1.194	0.04

AIx75: adjusted augmentation index at a heart rate of 75 beats per minute; IVRT: isovolumic relaxation time; LAVI: left atrial volume index; NT-proBNP: N-terminal probrain natriuretic peptide.
