Inter-unit comparisons between all DG100 units for walking distances and speeds; the typical error of the estimate (TEE) and the coefficient of variation (CV) with 95% Confidence Interval [95% CI] are presented.

TEE is expressed in meters for walking distance and in km/h for walking speed. CV is expressed in percentage. Comparisons were performed from all pooled walking bouts (mean walking distance = 225 m).
