Figure 1. Bivariate Plot of the Relationship Between Raphe Nuclei Serotonin1A Binding Potential (BPF) and Lethality Rating of the Most Recent Suicide Attempt.

Figure 1

Participants include the 29 suicide attempters with major depressive disorder (MDD). Error bars depict associated SE; diagonal line, the fitted curve; and slope, the correlation. Lethality of the attempt was measured using the Beck Medical Lethality Scale (scores range from 0 to 6, and the scale scores to 8, which designates a fatal attempt) (F1,25 = 10.56; P = .003; R2 = 0.32). Displayed serotonin1A BPF estimates have been adjusted for sex and prior antidepressant use derived from the specific linear mixed-effects model examining the relationship of raphe nuclei serotonin1A BPF with lethality for all suicide attempters with MDD. For display purposes, 1 lower-lethality attempter with a very high serotonin1A BPF and SE is not included in this plot but was included in all the statistical analyses.
