Inclusion and exclusion criteria
A total of 112 patients volunteered to participate in this study. Prior to enrollment in the clinical trial, a survey was conducted to identify DH, and participants who did not meet the criteria were excluded. Initially, 78 participants (age, 18–65 y) were enrolled and underwent a primary screening assessment prior to the study using an air-blast test and were evaluated using the Schiff sensitivity score (Fig. CONSORT flow diagram of this clinical trial.Demographics and schiff scores at baseline.Mean age (95% C.I.)32.50(27.59, 37.41)31.91(25.77, 38.05)32.00(26.50, 37.50)Mean Schiff sensitivity score at screening (95% C.I.)2.01(1.65, 2.37)1.94(1.53, 2.35)1.94(1.53, 2.35)CI, confidence interval.
