Table 3. Multiple logistic regression model.

	Definitions	Coded value	Coefficient	Odds Ratio	95% CI (lower limit)	95% CI (upper limit)	P value
Mastication	Mastication is slow, hesitant, and delayed with ineffectual movements	0: intact, 1: inadequate	3.7	38.7	7.2	206.6	<0.001
Lingual motility prior to transfer	Tongue movement assisting mastication and bolus formation	0: intact, 1: inadequate	2.1	8.7	1.5	50.5	0.016
Aspiration	Entry of bolus into the lower respiratory tract	0: absent, 1: present	2.6	13.9	1.4	139.5	0.025
Total swallow time	From the initiation of mastication until the tail of the bolus passed through the upper esophageal sphincter	0: ≤10 sec, 1: >10 sec	2.6	14.1	2.9	67.2	0.001
