Data are Spearman correlation coefficient, with 95% confidence interval in parentheses. Global ileocolonic PET/CT score has been calculated on the basis of 5 intestinal segments from terminal ileum to rectum, whereas global PET/CT score has been calculated on the basis of 7 gastrointestinal tract segments from stomach to rectum.
