Scatter plots and regression lines for the relationships of EA with HVA and 5-HIAA in CSF.
Partial correlation test controlling for age and sex was performed in healthy controls (N = 54) and unmedicated patients with major depressive disorder (N = 13). Significant correlations of EA with (a) HVA and (b) 5-HIAA in CSF are shown. Abbreviations: EA, ethanolamine; CSF, cerebrospinal fluid; HVA, homovanillic acid; 5-HIAA, 5-hydroxyindoleacetic acid.
