Influence of psychoactive drugs on serum BDNF and NT4/5 levels at the time of diagnosis of colorectal cancer. Each data-point represents the result for one patient, horizontal lines represent the mean value and bars represent the standard deviation. Significant differences in the levels of BDNF (P=0.0059) and NT4/5 (P=0.0457) were obtained between patients with and without psychoactive drug treatment. *P<0.05; **P=0.01 as indicated. BDNF, brain-derived neurotrophic factor; NT4/5, neurotrophic factor 4.
