Figure 3: Scatter plots comparing individual values for (A) CSF DHPG vs. NE, (B) CSF MHPG vs. NE and (C) CSF MHPG vs. DHPG across all subjects (N=130).
Lines of best fit with 95% confidence intervals are shown. Abbreviations: DHPG=3,4-dihydroxyphenylglycol; MHPG=3-methoxy-4-hydroxyphenylglycol; NE=norepinephrine. There are strong positive inter-correlations among the 3 central noradrenergic indices. The lines of best fit have their y-intercept values above the origin.
