Whereas elevated IL-1β showed a non-significant inverse relation with PTSD (r(34) = −0.11, p = 0.52), IL-1β showed a non-significant direct relation with depression (r(34) = 0.28, p = 0.10; Z* =−3.12, p < 0.01) and a non-significant positive trend with anxiety (r(34) = 0.07, p = 0.67; Z* = −2.09, p = 0.04). The gene discussed is IL1B; the disease is depressive symptom measurement.
