Identification of the best model to predict swallow safety using Akaike’s information criterion

	Condition (With Or Without Capsaicin)	Bolus Size	ΔAIC
Model 1	+	+	0
Model 2		+	29.2301
Model 3	+		144.5859

The symbol “+” indicates that a given variable is considered when assessing the model. The model with the lowest AIC value (in this case, Model 1) is the most supportive, and is assigned a ΔAIC of zero. The difference between the best model’s AIC value and each other model’s AIC value gives the ΔAIC values for less supportive models. AIC, Akaike’s information criterion.
