Figure 2. Bivariate Plot of the Relationship Between Raphe Nuclei Serotonin1A Binding Potential (BPF) and the Beck Suicide Intent Scale Factor 1 Score in Suicide Attempters.

Figure 2

Participants include the 29 suicide attempters with major depressive disorder (MDD). Error bars depict associated SE; diagonal line, best fit; and slope, correlation. Factor 1 indicates lethal intent (scores range from 0 to 12) (F1,25 = 10.63; P = .003; R2 = 0.32). Displayed serotonin1A BPF estimates have been adjusted for sex and prior antidepressant medication status derived from the specific linear mixed-effects model examining the relationship of raphe nuclei serotonin1A BPF with the factor 1 score in 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.
