Text: Piperine improved the safety of swallow by : (a) reducing the prevalence of unsafe swallows by -34. 48 % (P = 0. 004) at 150 M and -57. 19 % (P < 0. 001) at 1 mM, and the severity score of the penetration-aspiration scale from 3. 25 0. 51 to 1. 85 0. 27 (P = 0. 003, 1 mM) ; and (b) shortening the time to laryngeal vestibule closure from 0. 366 0. 024 to 0. 270 0. 022 s with 150 M piperine (P < 0. 001) and from 0. 380 0. 032 to 0. 306 0. 028 s with 1 mM piperine (P < 0. 05).
