Influence of suicide on correlation between age and serotonin transporter (SERT)- immunoreactive (ir) axon length density in layer VI of the orbitofrontal cortex for control and depressed subjects. All control subjects (N=17) are represented by circles and solid line, subjects with major depressive disorder dying by suicide (MDD, N=8) are represented by open triangles and short-dashed line, and subjects with MDD dying by other causes (N=10) are represented by closed triangles and long-dashed line. There was a significant negative correlation between SERT-ir axon length density and age in MDD-non-suicide (r= −0.813 p<0.005) but not in MDD-suicide (r= −0.668 p>0.05). There was no significant correlation (r= 0.03, p>0.05) between SERT-ir axon length density and age in control subjects.
