Table 3 Results of multiple linear regression of the association between DII and disease activity as continuous variables, for CD and UC

From: The association between inflammatory potential of diet and disease activity: results from a cross-sectional study in patients with inflammatory bowel disease

   CD (n = 168) UC (n = 161)
β-coefficient (95% CI) p-value β-coefficient (95% CI) p-value
DII Crude 12.96 (4.74–21.18) 0.002 0.145 (− 0.134–0.424) 0.307
  Adjusted* 11.86 (3.14–20.58) 0.008 0.062 (− 0.236–0.361) 0.681
  1. Abbreviations: CD Crohn’s disease, UC Ulcerative colitis, DII Dietary inflammatory index, CI Confidence interval
  2. CD disease activity scores can range from 0 to > 450 and UC disease activity scores can range from 0 to 19
  3. Bold values are significant
  4. *Adjusted model: adjusted for age (years), age at diagnosis (years), gender (m/f), BMI (kg/m2) and education level (low/middle/high)
