Intensity ratings for 1M sodium chloride (mean ± SEM), 1M sucrose (mean ± SEM), 32mM citric acid (mean ± SEM), and 1mM quinine hydrochloride (mean ± SEM), applied bilaterally to the tongue tip (fungiform papillae) and to the back of the tongue (circumvallate papillae) among 2 rs34160967 genotype groups (0.25 AA/AG and 0.75 GG), controlling for age, sex, and intensity of tones as a cross-modal standard; [F (4, 262) = 2.02, P < 0.10], with significant pairwise comparisons shown. Different superscript letters a, b indicate significant differences at least P < 0.05.
