Correlation between improvement in quality of life and score on bitter taste test. There is a signification correlation only in nonpolypoid patients (p = 0.03, R2 = 0.15; for polyp patients, p = 0.45 and R2 = 0.01). Only subjects with both a taste test and T2R38 genotype are included in the graphic. AVI = nonfunctional receptor haplotype containing alanine, valine and isoleucine; ns = not significant; PAV = functional receptor haplotype containing proline, alanine, and valine; PTC = phenylthiocarbamide; SNOT-22 = 22-item Sino-Nasal Outcome Test.
