4. Fig 3
Loading coefficients from the first principal component of the Berg Balance Scale over time for the full sample for each item difficulty grouping (left panel = simple items, center panel = moderate items, right panel = difficult items). Center and right panels have broken y axes to better display the longitudinal pattern of loading coefficients for moderate and difficult items.
