Effect of NQO1P187S, NQO2L47F and apoE genotype distribution on CoQ
plasma levels. CoQ10 plasma levels before (T0) and after (T14) ubiquinol supplementation (150 mg/day) in humans are shown. Values are mean ± SD and n numbers (genotype distribution) are given in brackets. Differences between two genotype groups were examined using Student t-test (*p ≤ 0.05) and between all genotypes using "test for linear trend" (ANOVA).
