From: Solanidine is a sensitive and specific dietary biomarker for CYP2D6 activity
Frequency distribution histograms of log solanidine concentrations (a) and log metabolic ratios (b–f). CYP2D6 gPM, gIM, gNM, and gUM phenotypes are depicted by colors. Insets show individual solanidine concentrations and metabolite to solanidine concentration ratios in CYP2D6 gPM, gIM, gNM, and gUM individuals (horizontal line, geometric mean; whiskers, 95% confidence intervals). gIM, intermediate metabolizer; gNM, normal metabolizer; gPM, poor metabolizer; gUM, ultrarapid metabolizer
