BBS, Berg Balance Scale; DGI, Dynamic Gait Index; SPPB, Short Physical Performance Battery; TUG, Timed Up and Go.

All values are presented as mean (standard deviation) except for fallers (percentage).

P value is for linear regression except for Fallers, where logistic regression was used.

P value adjusted for clinical characteristics.

Missing data for one participant in the no stenosis group.
