Table 3 Absolute numbers (cells/μl) of leukocyte subpopulations and plasma cytokine levels (pg/ml) in PTSD patients versus healthy controls

From: Posttraumatic stress disorder is associated with an enhanced spontaneous production of pro-inflammatory cytokines by peripheral blood mononuclear cells

  1. * Statistical significance for differences in means of immune parameters was assessed by nonparametric permutation tests, using 10,000 random permutations of residuals under the reduced model.
  2. # Statistical significance was lost after correction for multiple comparisons with Holm’s stepwise procedure.
