Figure 5. 5-HT1A receptor binding is lower in male SIDS cases.

Graph comparing 5-HT1A receptor binding density measured with 3H 8-OH DPAT autoradiography in the raphé obscurus in male and female SIDS cases compared to controls infants. 5-HT1A receptor binding density in male SIDS infants is significantly lower compared to female SIDS infants (*p=0.04). 5-HT1A receptor binding in both male (p=0.02) and female (p=0.05) SIDS infants is significantly lower compared to controls.
