  • * Excluding perforations.

  • ** For cumulative inflammatory burden of ESR, low tertile: ≤ 15,000 mm/h, mid tertile: > 15,000 to ≤ 45,000 mm/h, high tertile: > 45,000 mm/h.

  • *** For cumulative glucocorticoid exposure, low tertile: ≤ 1500 mg, mid tertile: > 1500 to ≤ 7000 mg, high tertile: > 7000 mg. Statistically significant associations (p < 0.05) are shown in bold type. HR: hazard ratio.
