Plasma concentrations of TRP-derived metabolites in abstinent CUD-patients and control subjects. Plasma concentrations of (a) TRP, (b) KYN, (c) KA, (d) QA and (d) 5-HT were determined in the cocaine group and the control group. Bars are estimated marginal means and 95% CI. Data were analyzed by ANCOVA. (*)p < 0.05 and (**)p < 0.01 denote significant differences compared with the control group.
