Odds ratio for slip-related falls for all predictive variables of slip outcome

Predictive variables SD Odds ratio 95% CI
Feasible-stability-region measurement 0.048 1.74 0.96–3.16
Margin of stability 0.055 1.22 0.66–2.26
Floquet multiplier 0.044 1.26 0.69–2.32
Lyapunov exponent Short-term 0.516 1.14 0.52–2.51
Long-term 0.041 1.22 0.68–2.20
Gait parameters Step length (m) 0.066 1.27 0.71–2.28
Step width (m) 0.029 1.50 0.92–2.93
Step time (sec) 0.019 1.11 0.52–2.41

The odds ratio indicates the factor by which the fall probability increases with an increase (for Lyapunov exponents and gait parameters) or decrease (for the feasible-stability-region measurement, margin of stability, and Floquet multiplier) of 1SD in the variable across all subjects.

CI: confidence interval.
