CBLN1 and tuberculosis: The results of the nonparametric test among groups showed that the plasma abundance of five lipid metabolites in patients with TB presented significant statistical difference (P < 0.001), including LPA (0:0/16:0), LPA (0:0/18:0), Cer (d18:1/24:0), CerP (d18:1/20:3), and LPE (0:0/22:0).
