Figure 2. Longitudinal course of innate cytokine production and monocytes.

Longitudinal course LPS-induced Factor 3: innate cytokine production (A); and monocyte counts (B), as assessed before deployment (T0), 1 month (T1) and 6 months (T2) after return from deployment. The course of the group with depressive symptoms at T2 (n = 69) is depicted by the black circles (mean + SEM). The course of the group without depressive symptoms at T2 (n = 664) is depicted by the white rectangles (mean + SEM).
