Table 2:

Structural equation model outputs relating each posture or gait domain to FOG. For each domain, both fOg severity (measured as FOG ratio with natural log transformation), and dichotomous (presence of fOg) models are presented.

Latent Variable (domain)			95% BC CI
	Model	Cov	LB	UB
Gait	FOG Severity	−.223*	−.594	−.001
	Dichotomous	−.206*	−.276	−.004
Anticipatory postural response (APA)	FOG Severity	−.505*	−27.206	−.005
	Dichotomous	−.259*	−.614	−.004
Reactive Step	FOG Severity	−.003	−.401	.174
	Dichotomous	−.093	−.220	.002
Posture	FOG Severity	.122	−.062	.462
	Dichotomous	−.019	−.140	.037

Note: BC CI = Bias-Correct Confidence Interval computed using bootstrapped standard errors from 500 bootstrap resamples.

^*Significant at α = .05 as 95% BC CI does not contain 0.
