Physiological signs (symptoms) (N/trials, %) observed on fluoroscopy by two independent blinded speech-language pathologists (SLPs I and II). PPE: premature pharyngeal entry, ASR: absent swallow response, DSR: delayed swallow response, APS: aspiration prior to swallow, RPC: reduced pharyngeal contraction, RLE: reduced laryngeal excursion, REI: reduced epiglottic inversion, IAC: inadequate airway closure, PLV: penetration laryngeal vestibule, PSR: pyriform sinus residue, VLR: vallecular residue, ADS: aspiration during swallow, RPC: reduced pharyngeal contraction, APS: aspiration prior to swallow, REI: reduced epiglottic inversion, ASR: absent swallow response, PWR: pharyngeal wall residue, CPD: cricopharyngeal dysfunction, AWS: aspiration with swallow.

Note: Considering also salient symptoms from ORIG SPL (not represented here), PPE amounted to 95 and 92 % for patients #s 1 and 2, but varied as 93.8 and 40 % for VLR and 93 and 40 % for PLV respectively. In patient # 1, RPC was 63 % and IAC 49 % for patient # 2. Interreliability correlations between SLPs I and II varied (%) as 99 for PPE, 59 for DSR, 98 for PLV, 76 for VLR and 77 for PSR.
