Figure S1 - Development of an Umami Taste Sensitivity Test and Its Clinical Use

Histograms (upper part) showing distribution of the umami sensitivity for the patients before treatment (red) and the controls (blue). Abscissae: concentrations of the aqueous MSG solutions (1, 1 mM; 2, 5 mM; 3, 10 mM; 4, 50 mM; 5, 100 mM; 6, 200 mM; 7, >200 mM). Ordinates: number of the participants who correctly recognized MSG at each concentration of MSG, and the ROC curves (lower part) to assess the diagnostic value of the umami taste sensitivity test (See Table 4). AT, anterior tongue; PT, posterior tongue; SP, soft palate. (PDF)
