  1. Values are the mean (95% confidence interval)
  2. * The median Homeostasis Model Assessment for insulin resistance (HOMA-IR) value at baseline was used to assign patients into low (HOMA-IR ≤ 3.18, n = 31) or high (HOMA-IR > 3.18, n = 30) insulin resistance group
  3. † Paired t-test for comparison of values between baseline and after 12 weeks of anti-TNF treatment
  4. # Statistical comparisons were performed using log transformed values
  5.
