  1. Mean ± SE. p a-values derived from a One-way ANOVA. p b-values were adjusted for age, sex, smoking, and drinking. p c-values were adjusted for age, sex, smoking, drinking, and BMI. All p < 0.05 marked with letters were derived from Bonferroni post hoc test at p c-values; no significant differences are marked with the same letter and significant differences are marked with different letters
