Table 3 Incidence of intestinal complications (overall and segregated types) in patients with ulcerative colitis considering all population at risk

	Total of events	First event¹ (n)	PY²	IR (95%CI)
Overall	6711	3616	141997.40	2.546 (2.464-2.628)
Associated disease (ICD-10-related)	3766	1372	146806.44	0.934 (0.885-0.983)
Procedure-related	1324	1125	148326.75	0.758 (0.714-0.802)
Colitis-related Hospitalization	1791	1426	147412.62	0.967 (0.917-1.017)

Incidence rate = n of patients with event/patient year × 100.

¹Counted only the first intestinal complication (claim), but the patient could present with more than one IC (represented by the sum of the first claim).

²Patient year = sum of time of all patients under risk, since index date up to first IC or last available data.

ICs: Intestinal complications; IR: Incidence rate; ICD: International Classification of Diseases; PY: Patient year; UC: Ulcerative colitis.
