Suprathreshold intensity ratings of pre-diabetics (n = 40), diabetics (n = 40) and normoglycemic controls (n = 34). The intensities (mm) of perceived sensations for four suprathreshold concentrations (0.0202, 0.064, 0.202, 064 mol/L) of sucrose in pre-diabetics, diabetics and normoglycemic controls are shown. Tukey’s post hoc analysis confirmed that intensity ratings of diabetics were significantly lower (p < 0.001) compared to normoglycemic controls.
