Table 3 Mean age (SD) and mean levels (SD) of peripheral circulating cytokines in healthy volunteers and a subgroup of matched patients

From: The effect of trauma and alcohol on the relationship between level of cytokines and depression among patients entering psychiatric treatment

Variable Matched patients Healthy volunteers Sig.a
n = 19 n = 19  
Age (years) 42.5 (7.9) 28.8 (5.4) <0.001 b

  1. Note: aSignificance levels were tested by the Mann-Whitney U test. bPatients were older than the healthy volunteers. c+d Levels of TNF-α and MCP-1 were higher in patients
  2. Both healthy volunteers and matched patients were male
