Determinants of disease-specific knowledge among children with inflammatory bowel disease and their parents: A multicentre study

Table 3 Hierarchical linear regression for patient’s inflammatory bowel disease-knowledge inventory device score as an independent variables (model 3; details of model 1 and 2 are shown in Supplementary Table 2)

Surgical therapy		1.26 (0.76)	0.10	0.098
Raw/Corrected R2		0.311/0.269
F for change in R2		1.108
P value for R2 change		0.35

P value for the significance of the independent variable in the multivariate model. Dependent variable: patient’s IBD-KID score, model assessment: model 3 – df = 14, F = 7.562, P < 0.001. IBD-KID: Inflammatory bowel disease-knowledge inventory device; B: Unstandardised regression coefficient; SE: Standard error; Beta: Standardised regression coefficient; sec.: Secondary education.
