Effect of masticatory stimulation on the quantity and quality of saliva and the salivary metabolomic profile
Fig 1
Heat map of salivary metabolite concentrations.
Red, white, and blue indicate relatively higher, average and lower concentrations, respectively. Those identified by the black box (bottom of the figure) were from the stimulated saliva samples, and the others were from the unstimulated samples. Clustering was conducted using Pearson correlation. Metabolite names are colored depending on the corrected P-values between the 2 groups.
