Table 4. Multivariate Cox regression modelling of left atrial variables adjusted for left ventricular ejection fraction.

Variable Multivariable hazard ratio P value
LA reservoir strain 0.920 (0.873–0.969) 0.002
LA booster strain 0.872 (0.774–0.983) 0.025
LAEF 0.959 (0.928–0.992) 0.015
LAVImax 1.030 (0.999–1.061) 0.055
LAVImin 1.040 (1.007–1.073) 0.016

Data in parentheses are 95% confidence intervals. Each hazard ratio is derived from a separate model containing the LA parameter and left ventricular ejection fraction. LA, left atrial; LAEF, left atrial ejection fraction; LAVImax, maximum indexed left atrial volume; LAVImin, minimum indexed left atrial volume.
