For the ST fast pace, the multiple linear regression model for gait speed was significant ( p = 0.02, Table 2 ), with a variance resolution of R 2 adj = 22%, driven by the MDS-UPDRS III (β = −0.27, p = 0.04) with a moderately negative post-hoc correlation (ρ = −0.31, p = 0.02, Figure 3A ) and a negative trend for use of a walking aid (β = −0.27, p = 0.06) with a moderate negative post-hoc correlation (ρ = −0.36, p = 0.004, Figure 3A ).
