Fig. 4. Correlation coefficients between IDO levels and TNF-α and INF-γ levels.
A There was a significant positive correlation between serum IDO levels and serum TNF-α levels in all schizophrenia patients. B The change in IDO levels showed a significant positive correlation with the decrease in TNF-α levels in the celecoxib group. C The change in IDO levels showed a significant positive correlation with the decrease in INF-γ levels in the celecoxib group. P < 0.05.
