Abstract
INTRODUCTION: The symptoms and comorbidities associated with ulcerative colitis (UC) add to the disease burden. Long-term assessment of the comorbidities associated with UC is needed. The objective of this study was to evaluate UC-related comorbidities, including opioid use as a proxy for pain diagnosis, among patients in the United States. METHODS: This was a retrospective matched cohort study. Working age adults with UC (≥2 independent claims with a UC diagnosis ≥30 days apart and within 1 year; first UC diagnosis was the index date) and controls without diagnosis for inflammatory bowel disease (IBD; random index date) were identified in a US healthcare claims database (OptumHealth Care Solutions, Inc.) of privately-insured patients (01/1999-03/2017). UC patients were matched 1:5 with non-IBD controls using baseline characteristics, including the Quan-Charlson comorbidity index and cardiovascular disease. Comorbidities during the 12-month baseline period before the index date were reported. During the follow-up, the incidence of new comorbidity, including opioid use, was compared to the non-IBD matched controls by Kaplan-Meier (KM) rate with log-rank test. RESULTS: There were 9,353 UC patients and 46,765 non-IBD matched patients in the study sample. The average age was 46 years old, and 50% of patients were female. At baseline, the symptoms and comorbidities significantly higher in the UC cohort were pain, fatigue, and anemia (Figure 1). During the follow-up, the rate of new cases of cardiovascular disease was significantly higher in the UC compared to the matched non-IBD cohort, reaching 8.8% vs 7.8% at year 6, respectively (Figure 2). The rates of new cases of fatigue (4.7 vs 3.3%), anemia (4.8 vs 1.8%), respiratory disease (2.9 vs 1.8%), and anxiety (4.1 vs 2.6%) were also significantly higher in the UC cohort compared to the non-IBD cohort by year 6 ( P -value < 0.001). Rates of new pain diagnosis or opioid use cases were significantly higher in the UC cohort reaching 70.8% compared to 58.0% in the non-IBD cohort, by year 6 (Figure 3). CONCLUSION: In this large retrospective study with long follow-up, comorbidities occurred more frequently in UC compared to matched non-IBD patients. Notably, the rate of new cases of pain/opioid use was significantly higher in UC patients reaching 70.8% by the end of follow-up. These results suggest that patients with UC also have a higher rate of concurrent comorbidities, which add to the disease burden.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
