The change in salivary parameters for each group showing a lower stimulated saliva secretion rate and IgA secretion rate (cluster A in Fig. 2) and higher values (clusters B + C in Fig. 2). Salivary secretion flow rate (a) and (b), concentration of IgA (c) and (d), and the secretion rate of IgA (e) and (f). Panels a, c and e present the data in cluster A (n = 11) and panels b, d and f present the data in the clusters B + C (n = 12). Only the data without any missing value was used. Wilcoxon matched-pairs signed rank test (two-tailed) was used. *P < 0.05
