  1. TNF-α: tumor necrosis factor alpha, IL-6: interleukin 6, TNF-α and IL-6 monocytes*: measurements of the supernatant of spontaneous peripheral monocyte cultures.
  2. The values are presented as the means and standard deviations or as medians and quartiles. The statistical analysis was performed by t test or Mann–Whitney.
