Inclusion criteria
* Having at least one ICN visit with documented new use of ustekinumab * Participants with a documented Crohn's disease (CD) diagnosis at the time ustekinumab was initiated (that is, Baseline); If diagnosis at baseline is missing, then the diagnosis from previous visit within study window will be utilized * Having at least one ICN visit prior to the ICN visit when ustekinumab is first documented * Having received first dose of ustekinumab on or before June 22, 2019 * Having provided informed consent for use of ICN data for research purposes
Exclusion criteria
* Documented exposure to ustekinumab before enrollment in ICN (by chart review)
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Cohort 1: Percentage of Pediatric Participants with Clinical Remission at Week 52 | Week 52 | Percentage of Pediatric participants with clinical remission at Week 52 will be reported. Clinical remission is defined by short pediatric Crohn's disease activity index (sPCDAI) less than or equal to (\<=) 10. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Cohorts 2, 3, 4, 5, 6, 8 and 9: Percentage of Participants with Clinical Remission at Week 52 | Week 52 | Percentage of participants with clinical remission at Week 52 will be reported. |
| Cohorts 1 and 7: Percentage of Participants with Clinical Remission at Week 52 Evaluated by Ustekinumab Dose Bands | Week 52 | Percentage of participants with clinical remission at Week 52 evaluated by ustekinumab dose bands will be reported. |
| Cohorts 1 and 7: Percentage of Participants with Clinical Remission at Week 52 with No Corticosteroid Use | Week 52 | Percentage of participants with clinical remission at Week 52 with no corticosteroid use will be reported. |
| Cohorts 1 and 7: Percentage of Participants with Clinical Remission at Week 52 by PGA Score | Week 52 | Percentage of participants with clinical remission at Week 52 by Physician Global Assessment (PGA) score will be reported. |
| Cohorts 1 and 7: Change from Baseline in Height at Week 52 | Baseline and Week 52 | Change from baseline in height at Week 52 will be reported. |
| Cohorts 1 and 7: Change from Baseline in Weight at Week 52 | Baseline and Week 52 | Change from baseline in weight at Week 52 will be reported. |
| Cohort 7: Percentage of Young Adult Participants with Clinical Remission at Week 52 | Week 52 | Percentage of young adult participants with clinical remission at Week 52 will be reported. |
| Cohorts 1 and 7: Percentage of Participants Who Achieve Endoscopic Remission with SEMA-CD Score of 0 or 1 at Week 52 | Week 52 | Percentage of participants who achieve endoscopic remission with simplified endoscopic mucosal assessment for Crohn's disease (SEMA-CD) score of 0 or 1 at Week 52 will be reported. Endoscopic remission is defined as SEMA-CD score of 0 or 1. SEMA-CD mucosal disease activity score is defined as inactive = 0; minimal = 1; mild = 2-4; moderate = 5-9, or severe = greater than or equal to (\>=) 10. |
| Cohorts 1 and 7: Change from Baseline to Week 52 in Mucosal Disease Activity Measured with SEMA-CD Score | Baseline to Week 52 | Change from baseline to Week 52 in mucosal disease activity measured with SEMA-CD score will be reported. SEMA-CD mucosal disease activity score is defined as inactive = 0; minimal = 1; mild = 2-4; moderate = 5-9, or severe = greater than or equal to (\>=) 10. |
| Cohorts 1 and 7: Percentage of Participants that Discontinued Ustekinumab Use Among Participants who Initiated Ustekinumab Therapy at Week 52 | Week 52 | Percentage of participants that discontinued ustekinumab use among participants who initiated ustekinumab therapy at Week 52 will be reported. |
| Cohorts 1 and 7: Percentage of Participants with Occurrence of Inflammatory Bowel Diseases (IBD)-related Hospitalizations Who had Initiated Ustekinumab Therapy | Up to Week 52 | Percentage of participants with occurrence of IBD-related hospitalizations who had initiated ustekinumab therapy will be reported. |

| Cohorts 1 and 7: Change from Baseline in Body Mass Index (BMI) at Week 52 | Baseline and Week 52 | Change from baseline in BMI (measured with age and sex-specific z-scores) at Week 52 will be reported. |
