Values are presented as numbers and precentages (%). Event number of POST was number of patients who rated ≥1 on the numeric rating scale.
POST: postoperative sore throat, T2: immediately after removal of laryngeal mask airway, T3: one hour after removal of LMA, Group G: lidocaine viscous gargle, Group T: lidocaine viscous topical application on laryngeal mask airway, NRS: numeric rating scale (range 0-10; a higher score indicates worse pain)
↵† P-values based on the number of patients with NRS score of 0, 1, 2, 3, 4, and 5 as categorical variables.
