  • Values are ORs (99% CI) and corresponding p values.

  • The OR of disease deterioration for each variable is included. If no unit is specified, quantitative variables indicate ORs for 1 SD. Binary variables (yes/no) are distinguished by a ‘B’. Disease duration is indicated in years. Hospitalisation days refers to hospitalisations related to Crohn's disease.

  • Total Post-traumatic Stress (TPS) Model (457 (97.6%) valid cases): −2×ln(likelihood)=415; RE-experiencing (REX) Model (465 (99.3%) valid cases): −2×ln(likelihood)=434; Avoidance (AVO) Model (462 (98.7%) valid cases): −2×ln(likelihood)=419; Hyperarousal (HYP) Model (459 (98.1%) valid cases): −2×ln(likelihood)=431; Control Model (465 (99.3%) valid cases): −2×ln(likelihood)=455; −2×ln(likelihood ratio PDS/control variables)=40, p<0.001; −2×ln(likelihood ratio REX/control variables) =21, p<0.001; −2×ln(likelihood ratio AVO/control variables)=36, p<0.001; −2×ln(likelihood ratio ARO/control variables)=24, p<0.001.

  • BMI, body mass index; CDAI, Crohn's Disease Activity Index; TNF, tumour necrosis factor.
