Effect sizes (ES) for the differences between pwPD (at each H&Y stage) and HS for each of the 8 gait variables, 3 factor scores and the gait model (abscissa). The magnitude of each ES for each stage of the H&Y scale (ordinate) is marked in colours according to the palette shown on the right: dark redā>ā2, huge effect; redā>ā1.2, very large effect; orangeā>ā0.80, large effect; yellow 0.50ā0.79, medium effect; sand 0.20ā0.49, small effect; whiteā<ā0.20, no effect.
