From: Proinflammatory cytokine levels in fibromyalgia patients are independent of body mass index

  Healthy Volunteers Female (n = 25) FM Female (n = 64) FM vs. Healthy Volunteers
Age (years) 44.96 ± 10.01 47.07 ± 8.48 N.S.

  1. Values are presented as mean (± SD) except where otherwise noted.
  2. BMI = Body Mass Index; FM = Fibromyalgia patients; IL = Interleukin; N.D. = nondetectable; N.S. = not significant; N.A. = nonapplicable; TNF-α = Tumor Necrosis Factor - alpha.
