  1. Variables of the model; selected ICF categories that best capture different levels of self-perceived health of PVI along with their beta estimator (β).
  2. β1: beta estimates for ICF qualifier “1” (mild impairment/limitation/restriction/barrier/facilitator).
  3. β2: beta estimates for ICF qualifier “2” (moderate impairment/limitation/restriction/barrier/facilitator).
  4. β3: beta estimates for ICF qualifier “3” (severe impairment/limitation/restriction/barrier/facilitator).
  5. β4: beta estimates for ICF qualifier “4” (complete impairment/limitation/restriction/barrier/facilitator).
  6. §Supportive environmental factor = facilitator.
  7. #Hindering environmental factor = barrier.
  8. Empty stratum; beta estimator could not be calculated.
