Summary of receiver operator characteristic curve results for lingual physiologic capacity and derived functional lingual pressure thresholds associated with unsafe and inefficient swallowing in this cohort of 30 individuals with amyotrophic lateral sclerosis.

Swallowing Impairment	FLPT:	Area Under the Curve (95% C.I.)	Sensitivity (%)	Specificity (%)
Unsafe Swallowing	≤43kPa	0.82 (0.70, 0.98)	94%	61.5%
Inefficient Swallowing	≤46kPa	0.77 (0.60, 0.94)	85.7%	55.6%

Note: FLPT: Functional lingual pressure threshold. Unsafe swallowing: ≥3 worst Penetration-Aspiration Scale [21] score. Inefficient swallowing: ≥3% C2-C4² worst total pharyngeal residue. [29, 30]
