The dependent variable for quantile regression models was the Total Score of SwalQoL.
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
