	Multiple R.	Adjust R² (%)	R² (%)	R² change (%)	Sig. change
Model 1	0.24	4.95	5.57	5.57	F change = 8.94	p <.001
Model 2	0.27	6.63	7.42	1.85	F change = 9.42	p <.001
Model 3	0.29	7.03	8.17	0.75	F change = 7.14	p <.001
Model 4	0.39	13.41	15.07	6.90	F change = 9.06	p <.001

Model 1: This model included demographic factors, frailty and sarcopenia.
Model 2: This model included demographic factors, frailty, sarcopenia, removable denture and functional teeth.
Model 3: This model included demographic factors, frailty, sarcopenia, removable denture, functional teeth, plaque index and tongue coating.
Model 4: This model included demographic factors, frailty, sarcopenia, removable denture, functional teeth, plaque index, tongue coating, xerostomia, dysphagia, occlusal condition and masticatory performance.
