  1. Coeff: Coefficient, CI: confidence interval, CFS: Clinical frailty scale, FRAIL: Fatigue, Resistance, Ambulation, Illness, Loss of weight
  2. The dependent variable for quantile regression models was the Total Score of SwalQoL.
  3. Independent variables for Model 1 were Age, Sex, Presence of Dementia, Malnutrition, and CFS score, for Model 2 Age, Sex, Presence of Dementia, Malnutrition, and FRAIL Score, for Model 3 Age, Sex, Stage of Dementia, Malnutrition, and CFS score; for Model 4 3 Age, Sex, Stage of Dementia, Malnutrition, and FRAIL score
