  1. In all patients, correlations between DT and age and total protein were analyzed using Pearson’s correlation coefficient, and other correlation analyses were conducted using Spearman’s correlation coefficient. In patients with ADD, correlations between DT or RT, and age, BMI, total protein, zinc, and TDAS score were analyzed using Pearson’s correlation coefficient, and other correlation analyses were conducted using Spearman’s correlation coefficient. In patients with MCI, correlations between DT or RT and age, total protein, albumin, and zinc were analyzed using Pearson’s correlation coefficient, and other correlation analyses were conducted using Spearman’s correlation coefficient. In NDCs, correlations between DT and age, medications, salivation, total protein, albumin, and zinc were analyzed using Pearson’s correlation coefficient, and other correlation analyses were conducted using Spearman’s correlation coefficient
