  1. "a, b" were multiple comparison marks. When marked with different letters, it indicates the difference with statistically significant between the two groups. CD: Crohn’s disease; CT: computed tomography; CTE: computed tomography enterography; NIC: ormalized iodine concentration; VMI: virtual monoenergetic imaging
