Note. MD = muscular dystrophy; MS = multiple sclerosis; PPS = post-polio syndrome; SCI = spinal cord injury; Sex: 0 = male, 1 = female; β = standardized coefficient; Adjusted R² = a modification of R² that adjusts for the number of explanatory terms in the model. Values are slightly smaller than unadjusted R² values and are thought to better reflect population values.
