简要总结
Bio-naive participants are defined as the participants who previously have not received any biologics for Crohn's Disease (CD).The purpose of this retrospective study is to describe the endoscopic remission at week 24 among bio-naive participants with CD treated with ustekinumab in China.

研究组 & 干预措施
Bio-naive Participants With Crohn's Disease (CD)
Participants with CD from inflammatory bowel disease (IBD) database who received ustekinumab from 20 May 2020 to 16 September 2022 in the real-world setting in China will be observed in the study. Only data available per routine clinical practice will be collected within this study.
干预措施: Ustekinumab (Drug)
结局指标
主要结局
Percentage of Participants With Endoscopic Remission at Week 24
时间窗: Week 24
Endoscopic remission: simple endoscopic score for crohn's disease (SES-CD) less than or equal to (\<=) 2, total SES-CD \<=4, a decrease in total SES-CD greater than or equal to (\>=) 2 from baseline, and no subtotal SES-CD \>1 for each endoscopic parameter (for isolated ileal, ileocolonic and isolated colonic CD), rutgeerts score \<=i1 (for post-operation CD). SES-CD: assesses disease severity based on 4 endoscopic parameters across 5 ileocolonic segments. Total SES-CD = 0 to 56,higher scores = more severe disease. Rutgeerts score: assess postoperative disease recurrence with no lesions (i0); \<=5 aphthous lesions (i1); \>5 aphthous ulcers with normal intervening mucosa/patchy areas of larger lesions/lesions confined to ileocolic anastomosis (i2); diffuse aphthous ileitis and diffusely inflamed mucosa (i3); diffuse inflammation with large ulcers, nodules, and/or stenosis (i4).
