There is an error in the penultimate sentence of the first paragraph of the "Novel nicotine-dependent biomarkers" section. It should read: "Especially two sphingomyelins, SM (OH, COOH) C16:1 and SM OH C20:3, and one PC ae C38:2 had the most significant p-values in the Wilcoxon test comparing former smokers and non-smokers."
