2. Fig 1
Physical function model—1 month. Ovals represent latent variables, and rectangles represent measured variables. Single-headed arrows between latent and measured variables denote paths; numeric values are factor loadings. Curved lines represent associations, and numeric values correspond to correlations. Single-headed arrows to the left of each measured variable represent unexplained sources of variations, and numeric values correspond to error variances. Abbreviation: ADL, activities of daily living.
