SE, standard error; CD, Crohn’s disease; HBI, Harvey-Bradshaw Index; TNF, tumour necrosis factor.

aComplication refers to the first occurrence of a CD-related surgery, complication, or hospitalisation.

bRegression coefficients are presented before shrinkage [shrinkage factor = 0.92].

cRegression coefficients are presented before shrinkage [shrinkage factor = 0.90].

dStool frequency has a maximum value of 12.
