Independent predictors of six-minute walk distance in multiple linear regression analysis.

N = 424*	Beta (95% CI) [Estimated change in walk in m]	P
Female gender	−42.0 (−56.7, −27.4)	<0.0001
Age (10 year increase)	−14.9 (−21.2, −8.6)	<0.0001
LV lateral wall E/e′ (natural log increase)	−28.1 (−50.5, −5.6)	0.014
TRV (1 m/sec increase)	−22.8 (−41.8, −3.7)	0.019

^*Four outliers were excluded. R-square = 0.34.

Variables entered into model were age, BMI, gender, hemoglobin, TRV, LV lateral wall E/e′, and site.

Adjustment for site was performed using dummy variables.
