P-values are based on Mann-Whitney test or Kruskal-Wallis test with Bonferroni correction for multiple testing.
Arithmetic means are presented.
Nicotine (d2) half-life is measured in min, Cmax in ng/ml, AUC in min*µg/ml, and non-renal and total clearance in L/min.
Genotype frequencies are presented in the brackets.
OCT2 variation was examined with respect to nicotine renal as opposed to non-renal clearance (ml/min).
Abbreviation: SD, standard deviation; AUC, area under the curve; CL, clearance.
