	OR (95% CI)
Diagnosis (CD v UC)	2.3 (0.3–15.7)
Age at application	1.0 (0.8–1.1)
Disease activity
Continuous v 1 period	1.3 (0.2–9.0)
Continuous v fluctuating	2.2 (0.4–10.9)
Disease duration	1.2 (0.2–1.5)
History of surgery (yes v no)	0.4 (0.5–3.0)
History of immunosuppressive use	2.6 (0.2–27.5)
Sex (male v female)	1.4 (0.3–6.4)
Educational level*	—
Smoking (yes v no)	0.5 (0.1–2.0)

The values presented are the results of logistic regression analysis. No patient factors were significantly associated with encountering medical insurance difficulties.

*There was a trend towards higher risk in higher educated but due to cells containing zero, OR could not be calculated.

The p value of the likelihood ratio test was significant at 0.042.

OR, odds ratio; 95% CI, 95% confidence interval.
