  1. Data are presented as a mean (95% CI)
  2. Abbreviation. DII: dietary inflammatory index
  3. Model 1: Adjusted for energy intake
  4. Model 2: Adjusted for energy intake, age, fat mass, fat free mass, duration of disease, weight, and supplement use
  5. P-trends were obtained from the analysis of covariance
