OR - odds ratios; CI - confidence interval.

* Cohort of patients identified by administrative data (n = 697) includes all patients coded with UC + colectomy. The cohort used for chart data analysis excludes repeated admissions, patients without UC or colectomy, and unavailable charts (See Figure 1).
