3 Fig 2 Plots show interactions between subject fall group and environment for each gait parameter: The P values show the fall group by environment interactions, as determined by repeated-measures ANOVA adjusted for BMI, age, and MDNS score. (A) Step width variability. (B) Step time variability. (C) Step width-to-step length ratio. (D) Step length. (E) Step time. (F) Speed.
