The clustering results of participants based on the pattern of stimulated saliva flow rate and IgA secretion rate. The quantified values were divided by the averaged value of each sampling point and colored in black and white for relative higher and lower values, respectively, compared with their average. The color bar (at the upper left) indicates the fold change of each quantified values (0.5, 1.0 and 1.5 indicated fold change). Data at a line indicates the values collected at a time point and data at a column indicates the values for each subject. The top three lines and the bottom three lines indicate the rate of salivary secretion and IgA secretion rate data, respectively. Dendrogram (presented in tree form) indicates the similarity of each column, yielded by clustering analysis. Elucidation distance was used for the clustering algorithm, e.g. columns showing similar data patterns were aligned closely. Diseases and the use of medication are represented by solid dots. Abbreviations are presented in Table 2. Prominent clusters are labelled a, b and c
