  1. Mean gait parameter values (mean(SD)) in control and CiSCI cohorts at different BWS levels. F-statistics for simple BWS effect and group x BWS interaction are reported from the 2-way ANCOVA with one repeated factor and age as a covariate. The group-split F-statistics are reported as group effects and in case a significant effect was identified, a-priori simple contrasts to group baseline (0% BW) with a Sidak correction are indicated through bold formatting (p < 0.05). For CiSCIs, when parameters are side-dependent, only the result of the more affected side is reported unless results diverged significantly between more and less affected side
