Figure 4From: Kinematic variability, fractal dynamics and local dynamic stability of treadmill walkingDifferences between overground and treadmill walking. Effect size and confidence intervals. Black circles are the standardized effect size (Hedge's g), as reported in table 1. Horizontal lines are the 95% confidence intervals. The arbitrary limit of 0.5 (vertical dotted line) corresponds to a medium effect as defined by Cohen.Back to article page
